Hi,
I want to write some a GRASS geoprocessing script in Python. However Python
crashes at the first line when importing the grass scripting module:
from grass.script import *
>>> Unhandled exception while debugging...
Traceback (most recent call last):

DUPLICATE_SAME_ACCESS)
WindowsError: (6, 'Descripteur non valide')
[Dbg]>>>
I used GRASS 6.4, Windows XP, PythonWin
Any idea?
Thanks,
Pierre
