Let's see, where to begin.The scrolling is terrible, frustrating, does not work! I'm trying to use it right now!! I'm resorting to my keyboard and clicking the scroll bar to scroll!!! AAAHHHHHHHHH!!!The middle button can't be set as... A MIDDLE BUTTON!!!Forget about using this thing for ProE, UNIX emulator, or any other app that requires a middle button to actually perform as a middle button.I haven't been able to get the tilt to work.Worse of all, it's impossible to uninstall. You'd better have XP because you need to restore from a prior system state to get this little gem's drivers off your system.You can't uninstall, you can't install another Mouse's drivers.A mouse installation and configuration should not take hours.
