Hello all

Well this is very encouraging that someone has picked up the conversation
on OpenGl again. I really was never able to find the root cause of the
problem, I ported another demo and got different set of errors, usually
locking the computer up.

If you need anything, don't hesitate to ask. I would like to see a Euphoria
version of OpenGL.

Thanks
Paul Martin
