Have you tried the pre-compiled binaries for windows?

I'm running this one:
PyOpenGL-2.0.0.44.win32-py2.2.exe

available here, of course:
http://sourceforge.net/project/showfiles.php?group_id=5988

there is a section on upgrading from 1.5 to 2.0 in
the official online PyOpengGL manual here:

http://pyopengl.sourceforge.net/documentation/manual/upgrading.html

but i'm not using any of the commands listed in
this section, so none of these tips seem relevant.

This is why I suspect it's a TKinter problem or at least
an interaction between Tkinter and Pyopengl (thus my
suspicion of Tkinter's opengl context).

good idea.  i don't see any tk demo programs in my
installation of py2.2 except those with the .tcl extension.
I'm assuming these contain tk/tcl code, not tkinter code,
and therefore can't be run from python.  correct?

also, it seems like the only demo that could help
would be one that uses Pyopengl.

the pyopengl demos run, but only a few use tkinter, and
none of those build a gui class as a subclass of "Rawopengl"
(as my code does).

Anyone else out there taking this approach?

thanks.
