I have a tablet that works with both the stylus and a mouse. I use it when I'm working at my desk with my iBook (connected by USB). Recently I was staying with a friend, and hooked up to her Apple keyboard and mighty mouse (USB). In the mighty-mouse pref pane, it was set so the middle-click button would invoke exposé, but now that I'm home I'd like to turn that off. Unfortunately, the individual mouse pref pane doesn't appear under Mouse & Keyboard prefs with just my tablet mouse, and there is no such setting in the tablet pref pane.. Is there a way I can return my scroll-wheel click (middle button) to normal, so it doesn't invoke exposé?
