make sure that the drawing is set to 2D wireframe in both View menu and in
3D Orbit.
Also, if your graphic card is new, but not a Quadro, you could be having
some oddities that are harmless, but annoying when they do occur. A regen
will get rid of them.

All,
When I zoom in or zoom out, I get mysterious thick "lines" that suddenly
appear, or dissappear. I can't select them, and I can edit them. Also,
lines that I do have, dissappear. I use CAD 2005, with 2 gig of ram, and
just updated the video drivers.
Thoughts, ideas, suggestions?
