I installed XP Pro on a MacBook Pro running Boot Camp and Parallels. All works fairly well (slow though), but the mouse is sluggish. I'm using a Logitech MX 610 that works very well on Windows machines as well as on my Mac PowerBook G4. Any ideas here? A search of this forum only finds one unrelated topic. The mouse seemed sluggish even in Leopard before I installed XP but is worse now.
