Dear VMD users/gurus:

Could someone kindly advise me on the right set of graphics card
options (or non-existence thereof) for getting VMD to display
stereo with the NVidia Quadro 5000 graphics card?

Details: I am runnning the latest VMD (1.9) on a Dell workstation
with Windows 7 and the stated graphics card. The stereo tests
built into the card setup wizard show that the stereo works.
However, VMD shows only what appears to be the right or the left
part of the image when switched to the QuadBuffer stereo mode. No
switching/blinking: a plain image with its counterpart lost
elsewhere in the graphics card buffers.

I tried to duplicate the setup described in
http://cismm.cs.unc.edu/core-projects/visualization-and-analysis/setting-up-a-simple-stereo-system/
and it did not work. NB: in my card setup Wizard, VMD is marked
as an individual program with its own set of stereo options; I,
naturally, made those options match the default options for any
other stereo-employing program. Did not work. What's more,
starting VMD messes up the window manager: any window, when
moved, disappears from the screen but does reappear at a new
location on the screen when the focus is switched to another
window.

Has anyone had a similar problem? Is there a known combination of
options for display/video card that resolves that problem? Or is
VMD stereo simply incomaptible with the NVidia card? :(

Thank you! Any advice would be greatly appreciated!

Alexander.

PS. More data for this case. Here is what VMD outputs when it
starts:
