Defect ID:	uDG31/007
Summary:	API command window(position(x,y)) doesn't work
Description:	The API command window(position(x,y)) results in a Tcl/Tk Error: bad geometry specifier "x+y".
Work-Around:	None.
Affected:	uDraw(Graph) 3.0.x - uDraw(Graph) 3.1.1 ( all platforms )
Status:	Fixed internally

Defect ID:

uDG31/006

Summary:

uDraw(Graph) uses 100% CPU, if pipe is disconnected

Description:

If the pipe from an application to uDraw(Graph) is disconnected by a crashing application, uDraw(Graph) will use 100% CPU. Example:

echo <some commands> | uDrawGraph -pipe

Work-Around:

None.

Affected:

uDraw(Graph) 3.0.x - uDraw(Graph) 3.1.1 ( all platforms )

Status:

Open

Defect ID:	uDG31/005
Summary:	API command window(file_browser(...)) doesn't allow space in default directory
Description:	If the default directory path (fourth parameter) of the API command window(file_browser(...)) contains a whitespace, the directory will not be displayed in the file browser after opening. Instead the string "<default directory>" will be displayed.
Work-Around:	Unfortunately there is no real workaround for this bug in UNIX. The user can click into the Selection area of the file dialog and remove the " characters, than press CR. This should load the directory. In Windows put the default directory name into the file parameter (fifth parameter) like "C:/Dir/My Dir/Dir2/a", where a is some file name and not a directory. This will open the file browser in directory "C:/Dir/My Dir/Dir2".
Affected:	uDraw(Graph) 3.0.x - uDraw(Graph) 3.1.1 ( all platforms )
Status:	Fixed internally
Date:	Jun. 19, 2006

Defect ID:	uDG31/004
Summary:	Arrow heads of edges are not scaled
Description:	If the graph view is scaled by menu or API command all arrow heads of type "arrow" or "farrow" are drawn unscaled, if the edge is visible for the first time, which is especially true for all edges if the user opens a survey view.
Work-Around:	Go back to full scale or just change the scale a little bit, than choose the scale you want again. In survey view just choose menu "View -> Full Scale".
Affected:	uDraw(Graph) 3.1 - uDraw(Graph) 3.1.1 ( all platforms )
Status:	Fixed internally
Date:	May 10, 2005

Defect ID:	uDG31/003
Summary:	Command-Line option -startappl: command may not contain options
Description:	If uDraw(Graph) is called with command-line option -startappl and the filename of the application contains options (i.e. -startappl /bin `testappl -opt1 arg1 arg2 -opt2' as described in the online documentation), the application will not be started. The message "Error: Cannot start application" is shown in the footer.
Work-Around:	Use a small script, that calls your application with the necessary options (i.e. for the above example write the line "/bin/testappl -opt1 arg1 arg2 -opt2" in an executable file). Than start uDraw(Graph) with the option "-startappl $HOME applcall" if you've saved the script as $HOME/applcall.
Affected:	3.0.1 - uDraw(Graph) 3.1.1 ( all platforms )
Status:	Open
Date:	Apr. 21, 2005

Defect ID:	uDG31/002
Summary:	Tcl error on Windows: expected integer but got "bold"
Description:	Immediately at the startup of uDraw(Graph) an error message appears, saying: "Error while initializing user interface: expected integer but got "bold"". In the following details the function dv_tooltip_create is mentioned.
Work-Around:	This problem occurs, if a non-standard system font is used (i.e. a font named "9x15"). The workaround is to use a standard system font. If this is not possible for you, please contact us to get a fixed binary.
Affected:	3.0.x - uDraw(Graph) 3.1.1 ( Windows^® )
Status:	Fixed internally
Date:	Apr. 7, 2005

Defect ID:	uDG31/001
Summary:	Pressing keys PageUp and PageDown produces Tcl error
Description:	Pressing keys PageUp and PageDown in the uDraw(Graph) graph area always produces Tcl error 'invalid command name "tkScrollByPages"'.
Work-Around:	Don't use the above keys.
Affected:	uDraw(Graph) 3.1 ( all platforms )
Status:	Fixed in uDraw(Graph) 3.1.1
Date:	Mar. 7, 2005
