i'm using my girlfriends ibook 1.42, and dashboard (F11), expose (F8, F9, F10) will not work. if i made any shortcut to say shift, or the FN key by themselves, they work, but i cannot set expose to use any of the F-keys. i tried fooling around in mouse and keyboard area, and the shortcuts are registered. no go. even if i hold fn and hit the keys they don't work. any similar problems. i NEED expose to be remotely productive. thanks!
