Dave-

It's a  graphics driver problem.  I have a JRE bundle with
Java 3D 1.3.1 that you are welcome to use.  I just list it
on the web site as a different installer.  This only seems
to be an issue on Linux.  On windows, it will use DirectX
if it doesn't have the right version of OpenGL.

JOGL will not help because it requires the same version of
GL and GLX.
