GRASS net--
We're having a problem with v.digit's display window. When we enter
control points, chech registration, and define the digitizing window we
seem to have a scaling problem in one direction (either the X or Y,
depending on how we set up the map). V.digit creates a long skinny
window whose coordinates do not match the digitizing window we
entered. After this point, we can digitize normally, points returned
from the digitizer have the correct map coordinates, etc., but they
fall outside the bogus digitizing window on the graphics monitor.Please help! We have run out ideas.

Hi!!!
Some of our field office GRASS sites here in Michigan have reported this
same problem. I know that this sounds pretty simplistic, but the problem
turned out to be that on particular machines, when you set the first point
with the digitizer, there is about a second delay before it's "safe" to
move the puck to the diagonal corner to set the next point for the
digitizing window. What it's doing is selecting a point somewhere between
the point you actually want and the second corner you pick. What I tell
our folks to do is to select the first corner then wait for the "beep"
before moving the puck to the second corner.
Like I said, pretty simplistic, but the first few times someone called me
with this problem I had a heck of a time trying to figure out what was
wrong before it occurred to me that it could be something this simple !!
I hope that your problem is as under-whelming as mine was !! (For once !!)
Good Luck,
