Hi John,

I'm cleaning up the message thread a little bit for easier readability.

>>> OK, I've performed several tests and glut seems to be working fine on all
my configurations, in particular:

* PyOpenGL 3.0.0 on python2.6
* PyOpenGL 3.0.1b2 on python 2.6
* PyOpenGL 3.0.1b2 on python 2.5

They all seem to work, with the caveat being that all my tests were
performed on a Mac. Maybe someone else on the list who's using Windows XP
can reproduce the issue?

Cheers,
Alejandro.-
