[GRASS-user] Error running g.mapset in Windows

[Helena Herrera]

Greetings
I have a Python script that is suppose to use g.mapset to change the current
Mapset by running g.mapset but, everytime I run it I ge this error:
ERROR: Unable to read GIS_LOCK environment variable

What is this and what can I do to fix this? (I'm running in GRASS 6.4.0Svn
from June)


By the way in Linux (ubuntu) I get this error:
g.mapset mapset=Regional

Erasing monitors...
PNG: GRASS_TRUECOLOR status: TRUE
PNG: collecting to file: map.png,
GRASS_WIDTH=768, GRASS_HEIGHT=501
ERROR: PNG: couldn't open output file map.png


My problem is with the first one (windows)

Thanks
Helena
