Sigh. There needs to be a clinic on this topic. lol I used to multibox in live on an old XPS Dell laptop. Just opened 6 instances of the game, grouped up (took forever) and charged off to kill things using each little window to heal and recharge shields etc and of course, fire. LoL. And I loved the hell out of it.
Now my laptop (Alienware MI8) won't give me a clean windowed game; can't get the mouse of of the window...damn frustrating. Not a lot of time to fool with settings right now, but soon I'll have lots more time.
