Hi,

Can you please pass this on to the person who reported the problem:

This problem appears to be OpenGL related- I suspect, but am not yet certain,
that it's because our OpenGL on Suns is somewhat out of date (I plan to do
follow-up testing on this in the next few days).

In the meantime I have implemented a work-around that should make the problem
go away, by switching to a non-OpenGL graphics type by default. Maple tech
support says that that the only user-visible effect of this should be that
in rotating 3d graphics images, users will only see a box outline of the
shape during rotation, and the full image when the rotation is complete,
instead of seeing the image continuously during rotation.

Please let me and ajfox know if users report other graphics problems though,
particularly with 3d images.
