trackpad prefs pane missing
Having treated myself to a new Trackpad, I was surprised when it didn't show up as a pane in System Preferences. The only way I can open it is from "System > Library > Preference Panes > Trackpad.prefPane". I've tried reinstalling Mountain Lion but still no show. Any thoughts gratefully received.
