[GRASS-dev] Re: [GRASS-user] GRASS6.3 on Windows

[Michael Barton]

I've gone through and wrapped in catch statements all GRASS commands worth
wrapping (and probably some not worth it).

I also did a bit of cleanup to the help routines that I ran across.

I also added Carlos' get info buttons to the raster and vector layer panels.
These are quite handy.

There is a bug in v.what such that it kicks out the wrong stuff with its GUI
interface description. Only shows up from the GUI, but it would be nice if
it could be fixed.

Anything else GUI-wise broken and fixable that anyone has noticed?
