As I said before aux buffers are a WGL pixel format property. The pixel format selection code needs to take care of it. Right now it already tries to locate a format with aux buffers but it isn't failproof yet (wglChoosePixelFormatARB searches for an exact match or else for something with better capabilities; this is a little too strict for us) I'm working on better pixel format selection code but my time is very limited right now.
