Welcome!
----------------------------------------------------------------------
Welcome, and thanks for purchasing Visual Thought, the premier
cross-platform diagramming and flowcharting solution for UNIX and
Windows systems.  You can use Visual Thought to create many kinds of
drawings: software diagrams, flowcharts and other kinds of flow
diagrams, org charts, network diagrams, business graphics,
illustrations for documentation, and much more.  You can create
documents on any UNIX or Windows machine and transfer or open them
transparently on any other system.  You can leverage the consistent,
unified interface to reduce training requirements, replace
incompatible collections of platform-specific tools, and increase
productivity.

These release notes contain the important changes between versions 1.3
and 1.4 of Visual Thought, as well as other important introductory
information, such as how and where to get help.


Installation and Licensing
----------------------------------------------------------------------
Since Visual Thought 1.4 incorporates key-based licensing, you should
get (or already have) a license key from us to successfully run Visual
Thought with all features enabled.  If you don't have a valid license
key, Visual Thought 1.4 will still run; only the save and print
features are disabled.

If you don't already have a license key, please contact Confluent at
info@confluent.com or call us at 415-764-1000 or 800-780-2838.

Please feel free to send e-mail to vthought@confluent.com or call us
if you ever have any questions while installing or licensing Visual
Thought.

Complete instructions for installation and licensing are provided in
the "Installation and Licensing Guide" booklet accompanying the
CD-ROM.


Licensing Multiple Installations
----------------------------------------------------------------------
You can use Visual Thought floating licenses transparently across
multiple installations and all supported platforms.  For example, if
you purchase 5 floating licenses, you will be able to have 5
concurrent users on any combination of SunOS, Solaris, HP-UX, and
Windows machines using your same license key.

To serve floating licenses for Visual Thought 1.4 across multiple
installations (UNIX, Windows, or any combination thereof), the
important points to remember are:

 1. Normally, you should have exactly one license server process to
    serve all installations in your network.  If you use both UNIX and
    Windows versions of Visual Thought, we highly recommend that you run
    the license server on a UNIX workstation because of the greater
    robustness and reliability inherent in UNIX.

 2. The license directories of all installations must have identical
    copies of all license key files (e.g., 01.lic, 02.lic, etc.).  The
    license key files are installed in the license directory of the
    installation used by the license server.  They must be copied to the
    license directory of the other installations.

    The license key files are located in the following directories
    (assuming Visual Thought has been installed in the default location):

      UNIX:

        /usr/local/confluent/license

      Windows:

        C:\Program Files\Confluent\Visual Thought 1.4\license


Installation on UNIX
----------------------------------------------------------------------
On UNIX, to install Visual Thought 1.4 from CD-ROM, cd to the
top-level CD-ROM directory and type one of the following commands,
depending on which of the following files is present:

   ./install
   ./INSTALL*

To determine the products currently installed, cd to the top-level
installation directory in your filesystem and type:

   admin/install status


Licensing on UNIX
----------------------------------------------------------------------
On UNIX, to license Visual Thought 1.4:

 1. Execute the following command to start the license server:

       confluent_a start

 2. Execute the following command to install your license key:

       confluent_a key vthought

    Type your license key when prompted.  This will be 16-24 digits in
    groups of 4, separated by spaces, such as:

       1234 5678 9012 3456 7890 12

    You can obtain a report of installed license keys by executing the
    following command:

       confluent_a keys detail


Uninstalling on UNIX
----------------------------------------------------------------------
On UNIX, if you need to uninstall Visual Thought, cd to the top-level
installation directory in your filesystem and type:

   admin/uninstall


Installation on Windows
----------------------------------------------------------------------
On Windows, Visual Thought is installed from CD-ROM by simply
inserting it into your CD-ROM drive.  If your drive has autorun
capabilities, the setup program will automatically be run.  If not,
please run setup.exe in the windows subdirectory in the top-level
CD-ROM directory.

If you are installing from the archive file VT14.EXE, double-click on
the VT14.EXE icon to be led through the installation procedure.

Executing VT14.EXE will create a temporary directory named vt-14 that
is only used during installation and can be placed anywhere.  It also
runs setup.exe in the vt-14 directory to perform the installation.
After the installation is complete, you may delete the vt-14
directory.


Licensing on Windows
----------------------------------------------------------------------
On Windows, to license Visual Thought 1.4 with an evaluation or
personal (node-locked) license key:

 1. From the "Start->Programs->Visual Thought 1.4" menu, run the Admin
    program.  Alternatively, just double-click the Admin icon in the
    folder or program group created by the installer.  The program
    displays a window with the title "ConfluentLM: Create Key File".

    Type your license key into the field titled "Key:".  This will be
    16-24 digits in groups of 4, separated by spaces, such as:

       1234 5678 9012 3456 7890 12

    Click the OK button to install your key and dismiss the window.

To license Visual Thought 1.4 with a floating license key:

 1. From the "Start->Programs->Visual Thought 1.4" menu, run the
    Admin_server program.  Alternatively, just double-click the
    Admin_server icon in the folder or program group created by the
    installer.  The program displays a window with the title "ConfluentLM:
    Create Key File".

    Type your license key into the field titled "Key:".  This will be
    16-24 digits in groups of 4, separated by spaces, such as:

       1234 5678 9012 3456 7890 12

    Click the OK button to install your key and dismiss the window.

 2. Open the Control Panel and run the ConfluentLM applet.  The applet
    displays a window with the title "Confluent License Manager".

    Set Startup to "automatic".  This adds an entry to the Win.ini
    file that starts the license server when the system is booted.

    Click the Launch button if the window says the server is stopped.

    Click the OK button to close the window.

    You can use the ConfluentLM Control Panel applet to view and
    change the license server configuration by clicking the Settings
    button to open the Settings dialog.  Because of some problems with
    this utility, you should only use this dialog to view the
    configuration.  Do not click the OK button, as doing so may corrupt
    the configuration and prevent the license server from being started.
    The configuration is stored in the Confluen.ini file in the Windows
    directory, so a corrupted configuration can be corrected by directly
    editing this file.


Uninstalling on Windows
----------------------------------------------------------------------
On Windows, if you have installed a floating license key and are using
the license server, you must do the following before uninstalling:

 1. Open the Control Panel folder.

 2. Run the ConfluentLM applet.  The applet displays a window with the
    title "Confluent License Manager".

    Set Startup to "manual".

    Click the Stop button if the window says the server is running.

    Click the OK button to close the window.

The above steps are not necessary if you have installed an evaluation
or personal node-locked license key and are not using the license
server.

To uninstall Visual Thought on Windows NT 3.5:

 1. Make sure the Control Panel folder is closed.  If this is not done
    before the uninstall, the ConfluentLM applet will not be removed until
    the next system reboot and may interfere with a subsequent
    installation of Visual Thought.

 2. Double-click on the Uninstall icon in the Visual Thought 1.4
    program group created during installation.

To uninstall Visual Thought on Windows 95 or Windows NT 4:

 1. Open the Control Panel folder.

 2. Double-click on the Add/Remove Programs applet.

    Close the Control Panel folder.  If this is not done before the
    uninstall, the ConfluentLM applet will not be removed until the next
    system reboot and may interfere with a subsequent installation of
    Visual Thought.

    Select the Install/Uninstall folder.

    Click the Visual Thought entry to be removed.

    Click the Add/Remove button.

  laf                  Look-and-feel used for interface appearance and behavior

For more information on using preferences and detailed descriptions,
see the file note_preferences.txt.

* Colormap Problems on UNIX

Visual Thought can exhibit the following problems on UNIX related to X
colormap problems:

 - Colors flash when the window focus changes

 - Colors are dithered due to insufficient available colors

For more information and instructions to fix these problems, see the
file note_colormap.txt or consult the Guided Tour from the Help menu.

* Window Overlap on UNIX

The Visual Thought interface depends on access to multiple windows
(i.e., Main, Inspector, Palettes, Views, and various auxiliary
dialogs).  Visual Thought places these windows at positions designed
to provide for efficient user access.

On some UNIX window managers (e.g., vuewm, mwm), the default behavior
is to automatically place newly created windows at positions
determined by the window manager, without regard to the positions
specified by the application.  Such automatic placement of Visual
Thought windows results in window locations that provide a very
inconvenient user interface.

This problem can be prevented on UNIX by adding an entry of one of the
following forms to the X server resource database (e.g., by adding it
to the file ~/.Xdefaults) and restarting the window manager:

  Mwm*clientAutoPlace: false  (for mwm)
  Vuewm*clientAutoPlace: false  (for HP VUE)

After the window manager is restarted, the presence of one of the
above entries in the X server resource database can be verified with:

  xrdb -query | grep clientAutoPlace

* Using Audio on HP-UX

The use of Visual Thought audio capabilities on HP-UX requires that
the NCS Local Location Broker Daemon (llbd) and the audio server
(Aserver) be running on every system that is involved with the audio
operation.

The AUDIO environment variable specifies the host where Visual Thought
looks for the audio server.

For more information on using audio on HP-UX, see the file
note_hpaudio.txt.

* Technical Notes

A variety of technical notes are provided in the doc directory of your
installation.  The technical notes contain detailed information and
instructions to fix problems related to using Visual Thought.  You can
also always read the technical notes from the online Guided Tour,
accessible through the Help menu.

The following technical notes are currently available:

  File                  Subject

Changes Since Version 1.0
----------------------------------------------------------------------
If you are upgrading from the 1.0 release of Visual Thought, you
should read the file release_11.txt in addition to the remainder of
these release notes.  The file release_11.txt documents the changes
between the 1.0 and 1.1 releases.


Changes Since Version 1.1
----------------------------------------------------------------------
If you are upgrading from the 1.0 or 1.1 release of Visual Thought,
you should read the file release_12.txt in addition to the remainder
of these release notes.  The file release_12.txt documents the changes
between the 1.1 and 1.2 releases.


Changes Since Version 1.2
----------------------------------------------------------------------
If you are upgrading from the 1.0, 1.1, or 1.2 release of Visual
Thought, you should read the file release_13.txt in addition to the
remainder of these release notes.  The file release_13.txt documents
the changes between the 1.2 and 1.3 releases.


Changes Since Version 1.3
----------------------------------------------------------------------
The primary intent behind version 1.4 is to add new features and fix
problems.  The following major changes were made between the 1.3 and
1.4 releases.


Summary: Crash pressing a button during a drag from a palette

Visual Thought crashed when a button was pressed while an object was
being dragged from a palette.  A crash no longer occurs in this case.


Summary: Crash deleting objects during move and resize in the Select tool

Visual Thought crashed if the Del or BackSpace keys were used to
delete selected objects while the objects were being moved or resized
in the Select tool.  These keys are now disabled when the Select tool
is used to move or resize objects, so a crash no longer occurs.


Summary: Crash saving an EPS file to a readonly directory

Visual Thought crashed when the Export file chooser was used to save
an EPS file by double-clicking on a readonly directory.  A crash no
longer occurs in this case.


Summary: Crash printing on Windows without a default printer

Visual Thought crashed on Windows if no default printer was set.  A
crash no longer occurs in this case.


Summary: Slow startup on Windows 95

Visual Thought required a long time to start on Windows 95 when the
PATH environment variable contained root directory entries of the form
"<drive>:\".  Startup time is no longer affected by these PATH
entries.


Summary: Double-click on a directory in a save file chooser saved the file

Double-clicking on a directory in a file chooser while saving a file
saved the file, rather than entering the directory.  The file chooser
now works correctly when single- or double-clicking on a file or
directory.


Summary: Windows file associations were not used for attachment activation

Activation of attachments on Windows did not use the system file
associations to determine which application to use to activate the
attachment.  Windows file associations are now used to determine the
application.


Summary: New vt_new_from_template attachment option uses document as template

The vt_new_from_template option has been added to attachments.  This
option is specified by including the string "-vt_new_from_template" in
the Attachment Input Value field of the Inspector Attachment panel.
If this option is specified for an attached Visual Thought document,
the document will be used as a template to create a new document when
the attachment is activated.


Summary: Short document filenames on Windows caused file system conflicts

The use of short document filenames (i.e., 8.3 format) to represent
long filenames on Windows caused file system conflicts during saving
of documents and palettes.  Short filenames are now converted to long
filenames when documents and palettes are opened.  This is no longer a
problem.


Summary: New Printers configuration file for the printer list on UNIX

The optional Printers configuration file is now read, if it exists, to obtain the
printer list displayed in the Print dialog on UNIX.

By default, the printer list is obtained from the file /etc/printcap
on SunOS or by executing the lpstat command on Solaris and HP-UX.  On
large networks, the lpstat command can take a very long time to obtain
the printer list, significantly delaying display of the Print dialog.
Use of the lpstat command can be avoided by placing a list of printers
used by Visual Thought users in the Printers file.

The system version of the Printers file is read from the system config
directory in the Visual Thought installation directory (e.g.,
/usr/local/confluent/vt-1.4/solaris-2/config).  The user version of
the file is read from ~/.vthought.


Summary: New native EPS export formats with TIFF and WMF preview images

New native Encapsulated PostScript (EPS) formats with TIFF and WMF
preview images have been added to the Export file chooser.
Applications supporting these formats can use the PostScript to print,
while using the preview image to display on the screen.


Summary: New native Windows Metafile (WMF/EMF) export formats

The Windows Metafile (WMF) and Windows Enhanced Metafile (EMF) formats
are now generated as native export formats.  These are both vector
formats which allow inclusion of text and bitmaps.  Files in these
formats can be imported into most graphics-aware Windows applications,
such as Microsoft Word and PowerPoint.

Consult the FAQ file (FAQ.txt or FAQ.html) for information about WMF
limitations.


Summary: New copying of EMF to the Windows clipboard

Visual Thought graphics can now be copied in Windows Enhanced Metafile
(EMF) format to the Windows clipboard.  This allows the user to simply
copy or cut from Visual Thought and paste into most graphics-aware
Windows applications, such as Microsoft Word and PowerPoint.

Consult the FAQ file (FAQ.txt or FAQ.html) for information about WMF
limitations.


Summary: New multiple export formats

Format definitions in the Translators file can now specify export of
multiple single file formats.  This capability provides an efficient
method for generating multiple export files based on the same
document.

For more information, see the file note_export.txt.


Summary: New Preferences dialog and Preferences files

Visual Thought now supports an extensive set of user-settable
preferences in the Preferences dialog, opened with the
Options->Preferences... menu item.  Preferences may be configured for
an entire site with a system Preferences file and overridden
individually for each user with user Preferences files.

For more information, see the file note_preferences.txt.


Summary: Options->Preferences menu items replaced with preferences

The following items in the old Options->Preferences menu have been
replaced with preferences in the Preferences dialog and the
Preferences files:

  Menu Item                     Preference
  ---------                     ----------
  Turn AutoConnect On/Off       AutoConnect
  Turn Create & Connect On/Off  CreateConnect
  Turn Delete & Connect On/Off  DeleteConnect
  Turn Drop & Split On/Off      DropSplit

For more information, see the file note_preferences.txt.


Summary: Command line options replaced with preferences

The following command line options have been replaced with preferences
in the Preferences dialog and the Preferences files:

  Command Line  Preference
  ------------  ----------
  printclass    ColorPSImages
  encoding      EncodingLatin1

The old command line options should no longer be used.

For more information, see the file note_preferences.txt.


Summary: Preferences added for command line options

The following command line options now have associated preferences in
the Preferences dialog and the Preferences files:

  Command Line       Preference
  ------------       ----------
  printcmd           PrintCommand
  lflineterm         LineFeedTermination
  limittoscreen      LimitToScreen
  nosoundalert       NoSoundAlert
  informtranslators  InformTranslators

The old command line options can still be used.

For more information, see the file note_preferences.txt.


Summary: New preferences added

The following new preferences have been added to Visual Thought:

  Preference           Description
  ----------           -----------
  CreateNewDocument    A new document is created during startup
  DebugDefinitions     Alert notices are displayed during shape def parsing
  Personality          The "personality" customizing the startup interface
  RaiseOnDrop          A View is focused when palette objects are dropped on it
  SaveAsDirectory      Documents are saved as directories instead of files
  ShortSuffixes        3-character suffixes are used for saving documents
  WMFCurveApprox       Curves are approximated with polygons in WMF output
  WMFCurveResolution   The level of approximation when using WMFCurveApprox

These preferences are described elsewhere in these release notes.

For more information, see the file note_preferences.txt.


Summary: New saving of documents as files or directories

The new SaveAsDirectory preference controls whether documents are
saved as files (off) or directories (on).

Saving documents as directories allows document descriptions to be
saved as text (vthought.txt files) and images and sounds in documents
to be saved in native formats (GIF and AU).  These formats are
convenient for programmatic manipulation.

If programmatic manipulation is not desired, documents should be saved
as files instead to allow easier manipulation by the file system.

For more information, see the file note_preferences.txt.


Summary: New three-character file extensions for documents and palettes

The new ShortSuffixes preference controls whether long or short file
extensions are used for saving documents and palettes.

Normal extensions for Visual Thought documents are long (.vthought,
.vpalette, and .vtdef).  This preference can be turned on to use short
three-character extensions (.vtt, .vtp, .vtd).

For more information, see the file note_preferences.txt.


Summary: New personality customization during startup

The new Personality preference specifies the name of a subdirectory of
the definitions and startup directories from which documents are read
during startup.  This preference makes it easy to create customized
"desktops" for turnkey or vertical applications.  See the file
note_personality.txt for more information on personalities.

For more information, see the file note_preferences.txt.


Summary: New disabling of new document creation during startup

The new CreateNewDocument preference controls whether a new document
named Untitled-1 is created during startup.  It is sometimes useful to
turn this preference off when activating a Personality (via the
Personality preference), where the Personality provides a custom
configuration of Visual Thought documents during startup.

For more information, see the file note_preferences.txt.


Summary: New focusing of View windows when dragged palette shapes are dropped

The new RaiseOnDrop preference controls whether a View window is
raised and focused when a dragged palette shape is dropped in the
View.

For more information, see the file note_preferences.txt.


Summary: New preferences for control of WMF export output

The new WMFCurveApprox preference controls whether curves are
approximated with polygons in Windows Metafile output.

Visual Thought by default exports curves in the WMF format as Bezier
curves, which should allow import or paste with full resolution into
applications supporting WMF import.  While WMF is a standard vector
graphics exchange format, many applications (such as Word and
PowerPoint) do not handle the format in standard ways.

If pasting or importing a Visual Thought WMF image containing curves
into an application results in no image appearing, try turning this
preference on.  Visual Thought will render curves as many short line
segments, usually allowing the application to display the WMF image
while sacrificing some resolution.

The new WMFCurveResolution preference specifies the level of
approximation in pixels between curves and their polygon
approximations in Windows Metafile output if the WMFCurveApprox
preference is turned on.  The fineness of the approximation is
greatest when the curve resolution parameter is 0, coarsest when the
parameter is 100.

Consult the FAQ file (FAQ.txt or FAQ.html) for more information about
WMF limitations.


Summary: New debugging alert notices during parsing of shape definitions

The new DebugDefinitions preference controls whether alert notices
with debugging information are displayed during parsing of shape
definitions.  This preference is useful for debugging new shape
definitions.  See the file note_shapedefs.txt for more information on
creating shape definitions.

For more information, see the file note_preferences.txt.


Summary: Switching to Select tool disabled while creating objects

Visual Thought behaved incorrectly if the Esc key was used to switch
to the Select tool while creating objects with the Text or Shape
tools.  This key is now disabled when the Text and Shape tools are
being used to create objects.


Summary: Connections affected align and spread operations

The results of align and spread operations were affected by the
presence of selected connections.  Connections are now ignored during
align and spread operations.


Summary: Groups of groups were unselectable after opening a document

When a Visual Thought document was opened, some groups containing
groups could not be selected.  All groups can now be selected after
opening a document.


Summary: .vthought/.vpalette/.vtdef directories were treated as documents

Directories with valid Visual Thought document extensions (.vthought,
.vpalette, .vtdef), but no root name, were treated as Visual Thought
documents, rather than normal directories.  These directories are now
treated as directories.


Summary: New open connection arrowheads

The Arrow lists in the Inspector Shape panel now include a new set of
open arrowheads.  These were added to support UML notation.


Summary: Double rounded rectangle shapes were unrecognized

Double rounded rectangle shapes in the Jacobson palettes were not
recognized by Visual Thought.  These shapes are now recognized in the
new Jacobson palettes.


Summary: Empty imagemaps were exported if no objects had attachments
