This problem indicates that your OpenGL driver has bugs. If you are running
Solaris, you need OpenGL version 1.1.1 with patch 106022-03 or later.
To find out more about OpenGL patches for Solaris, visit:
If you are running Windows NT, make sure you have the latest drivers for your
graphics acceleration card. It is possible that even the latest drivers for
your card have bugs. If so, you should install Microsoft's OpenGL drivers,
These drivers will not use hardware acceleration, but seem to work fine
(although a bit slowly) with Windows NT.
Let the list know if you still have problems.
