TNT i found out WHY it does it...

happened to me 5 times and crashed my computer because i was testing it..

basically when you open IE7 (i assume you have) you can have more than one home page, well if you close the browser BEFORE any other home page is up it creates mass windows thinking its still there.

try it, anyone can do it, though you have to wait until it freezes to stop them.
