Hi all, New to Mac and i have to say that so far i LOVE it.....that being said... Here's a strange one. I have a Microsoft USB Keyboard. My problem is that as soon as I plug it into the computer and it's recognized, my mouse cursor goes to the top-left corner of whichever monitor is designated as the primary one. I'm on a 15" MacBook Pro Unibody, and sometimes use a dual-monitor setup (the issue still comes up when I'm only using the built-in LCD). I can move it away with the trackpad or an external mouse, but only for a second or two and then it snaps back to the corner again. The keyboard is a known good keyboard. I installed Microsoft's drivers for the keyboard, and that didn't change anything. Any ideas? I tried googling around, but have found nothing.
