Multiple Display Errata

I’m trying to run Q3 Arena under Win2000 with a GeForce4 MX 440 AGP as my primary display, and a Voodoo3 2000 PCI as my secondary display. I’m aware that OpenGL is not multiple-display compatible, however on certain occasions I am able to get Q3 to run. Most of the time, however, it just craps out with the “creating GL context: failed” message. I am unable to intentionally reproduce the conditions that allow it to run, so I can’t discern what is preventing it from running most of the time. I was wondering if anyone else had experienced this behavior at all.

Thanks in advance for all replies.
