I tried to give this a test on my old Windows laptop, but unfortunately the
graphics chipset doesn's support shared contexts, so I can't do more than
one Window..
If you give it a try with the **pyglet.options['debug_win32'] = True**
option set, does it reveal anything useful?
Also, I'd give it a try in the REPL, by manually typing everything in.
Basically just trying manually without the While loop: create two windows,
and switching to each.
I'll have access to a modern laptop with Win 7 in about a week or so, at
which time I can try to replicate/fix this.
