162.50 XP64 Quadro drivers: glGetString(GL_VERSION) returns null?

As it says. glGetString(GL_VERSION) returns null. This upsets GLEW greatly. Why is this?

Did you create GL context before glGetString(GL_VERSION) call?

Yes, I did. Precisely the same code works fine with the 160.02 drivers.

I did figure out, however, that this only occurs if you try to get an offscreen context directly from the WGL_gpu_affinity extension rather than by creating a hidden window.

I’d prefer to use gpu_affinity even with only one GPU, because it appears my framerate doubles that way for some reason.
