I get that error occasionally in Photoshop on my desktop (non-htpc) with a dual monitor setup. I never used to get the errors when I had one desktop. This happened with previously with an Nvidia 5700 and now with a 7600GT.
I *think* that some programs have a certain amount of transparency use (via hardware) which forces it to use DX9 even though the program isnt one you would normally associate with using DX9.
Whenever this would happen I have trouble dragging windows and issues with which window is in focus, but everything else seems to work OK. A restart of the application (photoshop in this case) or sometimes of the computer will solve the problem.
