[GRASS-user] trouble with dbf under WINGRASS

[Niels Thevs]

Dear all,

last week we had a workshop about WINGRASS (grass 6.3 CR$) and Q-
GIS (0.9.1) with students who use satellite images for their theses.
We used 20 computers all with the same software WINGRASS (grass 
6.3 CR$), MSYS, TCL 8.4, and Q-GIS (0.9.1). We encountered the following 
problems with the dbf files:
On 2 out of 20 computers no dbf file was written when we imported 
shape files into GRASS.
We were not able to use v.to.db to cvalculate areas of polygons.
The commands to add or remove columns did not work.
When we intersected vector layers about 4 out of 20 computers did 
not wirte a new dbf file for the intersection result.

One computer did not remove or alter masks. The GRASS shell under 
Q-GIS did not recognize the command r.mask.

All other things went very well. 

Regards

Niels
