Well, I've finally took some time to try this on Windows. Unfortunately, I
still can't reproduce the symptoms!

This is my system configuration:

>>> glGetString(GL_VERSION)
'4.1.0'

>>> glGetString(GL_RENDERER)
'GeForce GTX 465/PCI/SSE2'

>>> glGetString(GL_VENDOR)
'NVIDIA Corporation'

I'm on a 64-bit Windows 7 (Professional).

Is there anything I might be missing? Did you get any kind of reply from
NVIDIA?

I've read about them releasing OpenGL 4.2-capable drivers. Have you tried
those?

Best regards,
Alejandro.-
