Hi Ben, I had this happen to me one time too and thought I had too much running, didn't suspect anything wrong with XP/Saab/Gizmo - so didn't report it. Interesting, if I see it again I will grab the logs and screens as you have asked above. For the record, I have a very similar set-up Win764 8GB RAM + 1.5GB GPU with low install of Saab done. Sorry if I cannot offer more at this stage, but thought it might help to say "me too" if only to communicate it as not an isolated incident. Cheers James
