Interesting I had the same problem but on windows 7 .. well more or less same issues with Firestorm. I work on games and am working on a game right now that is far beyond anything graphically anything out can do, and I can obviously run my work project on max. In fact everything runs fine, i'd know, but SL just doesnt run anymore after years of running. Started with installed Firestorm, which I only did because of the GL issue currently going on with the official viewer that extends beyond 400 or 500 series cards, because people claimed the crashing was less, but that wasn't true. Anyway, don't need to explain things that are work related here and I'm not asking from help since i am the help.My problems too did only occur after running Firestorm.
