Thanks for the feedback. A few responses below.

This IS in GRASS. d.vect.chart is a GRASS module, not a QGIS module. In
QGIS, it is only available as a GRASS plugin. It is on the GUI menu in fact.
So it¹s odd that you didn¹t see it.

Actually this is not very helpful. I looked at the attached text file and it
is equally not helpful. TclTk indeed has it¹s own ³look² that may not be as
slick as some. But the usability is a lot more important. Switching from
TclTk to wxPython may make it look nicer, but that won¹t make it necessarily
more usable (though IMHO, it is no less useable than other high-end GIS
systems; but we¹d like to make it more useable than others).

Which version are you using. The GUI in TclTk has been updated in many ways
even since 6.2.0. So it would help to learn some specifics to see if they¹ve
already been addressed. The fact that you have a lot of crashes makes me
suspect that you are working with an early, less stable version. But it may
be due to other issues. Under what circumstances go you get a crash?
