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.
