Are you saying the occasional screen flash on full screen mode goes away for you when you shut off the Sound FX??

Andy you were right about third party codecs...
Uninstalling the SLD codec-pack solved all my sound and instability problems! And the screen flashes don't show up any more.
I can't say which codec exactly produced the problem, just uninstalled the whole thing and now is everything extremely well.
