problem with OpenGL on Windows Vista

[pamlinux at surfeu.ch]

Hello everybody,

It is a very long time since I reported my last problem, so congratulation to the wxPython developpers. Unfortunately, I bought a new PC and I had no other choice than Vista as OS. I have installed

python 2.5.1
wxpython 2.8.6.1 [1]
pyopengl 3.0.0a6 with easy_install (no exe available for python 2.5)

when I run the GLCanvas demo, I get the following :

c:Program FileswxPython2.8 Docs and Demosdemo>python  GLCanvas.py
Traceback (most recent call last):
  File "GLCanvas.py", line 15, in 
    from OpenGL.GLUT import *
  File "buildbdist.win32eggOpenGLGLUT__init__.py", line 4, in  
  File "buildbdist.win32eggOpenGLGLUTspecial.py", line 73, in 
AttributeError: 'NoneType' object has no attribute 'glutDestroyWindow'


I should say that this demo works perfectly well with the same versions of software on Windows XP. So, it must be a problem of Vista.

Any idea ?

Thank you very much in advance for any information or suggestion.
