Not sure that this would be Xp's fault... I can use Photoshop, Premiere, Illustrator and some other minor stuff like Winamp and ICQ at the same time without crashing. And I'm petty sure I don't have the best PC in this world (only upgraded it to 1 Ghz recently, and those stats were done before

) , nor the most RAM (384 only).
I'd rather look...
- Either at your footage (fotr instance, there's no way I can open DivX sources in my premiere without having them through Virtual Dub first)
- Or at some mnor crap like programs that install spywares that install other crap and so on, it makes any system become highly instable in thelong run
- Or, another thing I can see... You're using XP's Family version, not the Professional one
