Object Graphics+Win2k+nVidia Lockups

[Rick Towler <rtowler(at)u.washington.edu>]

Is anybody using object graphics on a Win2k machine with an nVidia based
graphics card?  If so, are you experiencing frequent lockups?  IDL will
lock up but I will still have mouse control. Then if I click on another
application the machine locks up tight.  I am assuming that this is a
display driver issue at this point.

This occurs regularly with my current application.  I have a 125x125
textured surface object "sea floor" and if I just fly around long enough
I lock up.  That's before I populate the scene with fish.

The application does run on our sun, but without a powerful graphics
adapter is unusable in real time. :( 

Any nVidia users out there?
