I think I've posted this before, but I've been banging my head on the wall trying to figure this one out. Here's the issue, sometimes I'll be in a drawing (large or small) and zoom, and everything disappears or turns blocky (like Atari)! If I is use cntrl+a to select all objects, they are all still in the drawing as I can see the grips. I've tried different video card drivers, only loading one lisp (with subroutines) to rule out any of my other routines are causing this to happens...and still the same :realmad:.
All I'm looking for is a nudge in the right direction for figuring this out.
Thanks,
Ron
