[PyMOL] 3D viewing issue

I had an old PC that a person was using pyMol and displaying 3D.  I needed to replace the hard drive and now I can't seem to get pyMol to display 3D.

I have the following hardware (That of course used to work just fine)

APG6000 Active Glasses & IR Emitter System
NuVision 60GX-T50 60GX-G5  (IR emitter)
Quadro 3700 graphics card.
DepthQ WXGA projector

This was running XP.

So I installed XP, latest Nvidia drivers and the latest 32bit version of pyMol.  The refresh rate on the projector is 120Hz the IR emitter is hooked up to the little DIN connector on the video board.  I set Stereo Enable to on.

When I start pyMol in Quad Buffered 3D, it says "Yep, I see your card 3D is OK" and when I choose to display in Quad Buffered Stereo it looks to the naked eye that there are the two images.  I have checked the IR is emitting (via phone camera) and have tried multiple glasses to rule out dead battery in them.

I imagine that I'm missing some silly setting or something.  (I have also tried this with Windows 10 and the latest version of pyMol with same results). I know this is an old setup, but it was working just fine before the rebuild.  I have no idea what I must be missing.  Any suggestions are welcome.  Thanks.
