[GRASS-user] 'Zoom to selected map(s)' doesn't

[Rich Shepard]

   During interactive editing of a vector map GRASS appears to have lost the
bounding box size of the displayed map. When the command to zoom to the
map's extent is given (either by the command window menu item or the display
window icon), the map is shrunk to a small blob at the top of the display
window.

   I have not figured out how to restore the proper behavior and would
appreciate a pointer on how to do this.

TIA,

Rich
