Just to be clear (I hate to keep adding to this thread, but here I go): I
am running an ATI Rage 128 chip on a Win98 system in 16 bit mode (with
hardware acceleration), and the demo works properly (purple text) on my
system. Of course, I am on Win98 instead of NT.

And to boot, I figured one more thing out. Sure, 24-bit mode works.
But it works SLOWLY! They even say in the readme that 3D acceleration
is only under 16-bit mode. This really stinks.
Does someone at Sun have a way to get ATI to fix this? I don't think I
can go to ATI with a Java3D example to get help. I don't really want to
make an OpenGL example just for the sake of getting tech support. I
would think that Sun would have more pull than me anyway.
BTW, anybody try this on an ATI running J3D DirectX?? I'm on NT :(

Lee,
Tested your test applet on a GeForce 256 system (16 bit color mode) and
your text does look "purple".
One more strike against ATI's drivers.
