Error with kPsychNeedFastBackingStore

1
Following the advice on enabling stereo rendering with 3d openGL, I
used the kPsychNeedFastBackingStore flag in OpenWindow. I got it
working fine at first, but once I restarted the computer, I got this
error happening all the time:

---

INTERNAL PSYCHTOOLBOX ERROR
error: PsychError_internal
general description: Unspecified error, probably a Psychtoolbox bug
specific description: Imaging Pipeline setup: Could not setup stage 1
of imaging pipeline.
module name: Screen
subfunction call: OpenWindow
file name: Common\Screen\PsychImagingPipelineSupport.c
function name: UNKNOWN
line number: 290

This is the line I'm using with viewMode = 9:

---
[win , winRect] = Screen('OpenWindow', screenid, 2, [], [], [],
viewMode, 0, kPsychNeedFastBackingStore);
---

I am really lost as to what caused it to work and then stop working
after restart. My best guess currently is that I had been running some
PsychDemos which changed some setting internally in Matlab but were
resetted when I restarted the thing. I'm running the latest graphic
card drivers (84.26) on this dual monitor (one analog, one DVI, both
75Hz 1280x1024) setup, with the latest revision of PsychToolbox. Any
ideas?

Thanks, I had to uninstall the antivirus on the workstation I'm on to
get the new drivers to install.
