vw7.8 OpenGL problem

I started a virgin 7.8 image in Win XP. Loaded OpenGL parcels and tried:
OpenGL.Lessons.Lesson00RenderContext new demo
VisualWorks just froze and had to be terminated with End Task from Windows XP.

How can I get OpenGL to work with VW?

All the best,
Aik-Siong Koh

7.8 and OpenGL runs fine for me in Windows7; may be something about Win XP is the problem. But regardless, what kind of card, what version of your display drivers, what version of opengl? Do you have any debug information? a stack dump?

Thanks.

Window Rendering:

Last line to get freeze:

Hey askoh,

The OpenGL interface won't work for anything below OpenGL 2.x -- here you've got a mobile graphics card running OpenGL 1.4; which can only do fixed-rendering. Your options are to get a better graphics card (not necessarily an option for everyone) or use the much older interface in Jun.
