On STC, only the bar at the bottom of the screen where the scale, crop region, etc. can be changed on the fly goes black and I get an error message that a display error has occurred. Doesn't happen for local saves. Always happens during the updating and/or regenerating phase after loading central is completed.

Haven't had this on my laptop, only on my desktop which is running

Pentium(R) 4, 2.8GHz
Nvidia Quadro FX 500, acceleration ull, no open GL
Revit 8.1

Anyone had similar experience? Ideas?

Thanks in advance....
