sudo touch /System/Library/Extensions
and it's working great. It really does incredible things for your trackpad. I have the Expose F9 key mapped to the upper left-hand corner, right click mapped to the bottom left-hand corner (ahh... a right click....) and vertical scrolling when I drag along the right 15% of the mousepad. You don't need two mouse buttons when you have SideTrack. And it's freeeeeeeeeee!
Again... do they get Inter-Karma points when I link to them multiple times?? SideTrack SideTrack SideTrack SideTrack SideTrack
