John,
I can understand having faster drivers correcting the problem, but if
the user does not have an accelerated 3D card then it should still run
in DirectX software-only mode, albeit slow. In this case, I can't rely
on driver updates to fix the problem.
I guess I still need to narrow this down to a test case that the Java3D
group can work with.
