I'm using a Logitech S10 Wireless Keyboard/Mouse combo. The keyboard works fine (the media controls sync with iTunes beautifully). The mouse however, has some issues. The clicking/scroll works fine. But whenever I use the scroll wheel and move it to the side (to scroll horizontally), the screen brightness starts to go down and doesn't stop. At what point is stops seems to be arbitrary; sometimes it'll go down only a few ticks, other times the whole way. Anyone have any clue as to what's going on?
