Help! My iBook's (500MHz, the one that was having monitor problems a few days ago) trackpad suddenly isn't working! The same thing for the mouse button. The interesting thing though, is that my attached Pro Mouse does work, and every 20 seconds or so, the trackpad works for about 2-3 seconds. During that time, the mouse button also works. I've tried restarting the computer, and since the Pro Mouse works, I doubt this is a software problem. The keyboard works fine. ANY help or suggestions of what might be wrong would be very greatly appreciated.
