Has anyone else had an issue with 3D geometry display and Windows 7?

I've tried opening a number of different projects with versions 3.61e (build
5653), 3.63 (build 6510), and 3.64 (build 7130) and the 3D geometry will not
display on my Windows 7 desktop, but will display just fine when I run the
models on an older XP machine with the same versions of eQuest. Anyone know
of a fix for this?

Thanks in advance,

Steven
