Hamish was working on that.

Still a problem. See:

$ g.region -p
projection: 0 (x,y)
zone: 0
north: 10000
south: 10
west: 50
east: 5000
nsres: 10
ewres: 10
rows: 999
cols: 495

$ v.digit map1&

  (a single "Zoom out" click)

$ g.region -p
projection: 0 (x,y)
zone: 0
north: 12068.929
south: -2058.929
west: -975.145
east: 6025.145
            ^^^
            those should be alligned to multiple 10

nsres: 9.99848408
ewres: 10.00041429
            ^^^
            those should be equal 10

are you using the latest CVS??? It should restore the starting region on
(normal) exit.

This bug should be kept open as the v.digit code should a) not be
changing the WIND file (if possible with mixed Tcl + C) and b) use
"g.region -a" like code when zooming so as not to corrupt background
raster resampling.
