So I don't use the magnifying glass much, since I can zoom in with the mouse wheel.

Today I hit G accidentally and was surprised with a white box instead of the magnification.

I could see dimensions when hovering over them, but otherwise it is just a blank white square.

I have some other graphics issues, so I would like to know if anyone else has a similar issue?

Running SW18 SP4 on a Dell configuration that has no certified driver yet...

If not, it is just another thing to add to my list of buggy stuff. Thanks.

EDIT: Oh and it works fine in model/assembly space.
