I haven't been able to reproduce the error on a Win98 laptop or a Win2K 
workstation.  The binary distribution seems to work fine on both of them.

Will keep trying,
Mike

Everything there sounds fine.

I've just added it, will show up the next time I refresh the web-site.

I'll look into finding someone to build a FontTools binary. IIRC it's
only a tiny little pyd that's written in C to speed up the equivalent
Python code.

I'm assuming you're trying the PyOpenGL demos. They don't really do all
that much compared to what OpenGLContext is doing, so OpenGLContext will
tend to find errors the demo doesn't (that's one of the major purposes
of OpenGLContext, actually).

Not really, that's a very generic error message. I don't really have
time to track it down today, but I'll try installing on my sister's
machine to see if I can duplicate the problem... probably be the weekend
before I can get some time free to work on it though. If you could try
running each of wxcontext.py (will likely fail due to a missing/bad
bitmap), glutcontext.py, and pygamecontext.py and report which of those
is producing the error it should help me narrow down where the error is.

Of course, if the error is actually in PyOpenGL, then they should all
fail. The error itself *looks* like a problem with PyOpenGL which
OpenGLContext just happens to be triggering. Still shouldn't happen,
and they're both my projects, so I'd like to track it down.

Have fun,
Mike

wxcontext.py fails with "invalid image"

glutcontext.py causes the crash i experience with the examples

pygamecontext.py fails with
"Pygame Parachute Traceback:
File "C:\PYTHON23\Lib\site-packages\OpenGLContext\renderpass.py", line
691, in
getProjection
Fatal Python error: (pygame parachute) Segmentation Fault"

Thanks for looking into this,
Daniel
