[winGRASS] grass native installation problem

[Jacques Charroy]

Hi,

I recently installed the native wingrass package on two computers. On 
one everything went well, but on the next one gis.m never managed to 
start, although GRASS starts alright. Upon starting gis.m I get an error 
box saying the following:

Error in startup script
Can't read "parts(n)": no such variable
while executing
"MapCanvas::zoom_new $mon $parts(n) $parts(s).......(more)
(procedure "MapCanvas::zoom_gregion" line 11)
invoked from within.......and so forth with 5 or six levels of function 
calls until:
invoked from within
(file "C:/msys/1.0/local/grass/etc/gm/gm.tcl" line 522)

Has someone else had the same problem? any ideas how to solve that?

Thanks,

Jacques Charroy
