[JGrass-users] some mixed questions

What do you mean by chose the georeference? What do you mean by
changes the original eastern? We need examples that can be reproduced.

Never had that problem before. We always suggest to create a new
mapset and work just in that.
What is the error message?

That is an old bug which we will not solve, since we are working on
the jgrass-udig version. However the manual states that the refresh is
needed to solve distortions that can occur in certain cases.

The multiple workspace support never came to full functionality.
Please browse also through the archives of the mailinglists, most of
the problems you see, were discussed already.

I suppose on planar, but that has to be asked to who wrote the module
(which from today will b on vacation for two weeks). Probably someone
else will answer.

>> 7) Is not possible to visualize many legends?

No

I don't think there is one and only way of doing things. That is why
they are logically separated. You have to know what you do before you
do :)

What do you mean by that?

JGrass has always been founded for the more scientific part and misses
some of the needed user interaction. Contributers are very welcome.
