v.digit

[Lee Thomas]

I just got v.digit working on our RS/6000 (yaa!), but for some reason
in the Window menu the selection for Display Overlay Map and 
Display Backdrop CELL Map doesn't have a menu choice.  Below is the menu
we see.  I need to be able to see our SPOT image sowe can digitize off it.
