Hi, I've found that almost few of my 3 finger gestures and none of my 4 finger gestures work... I've tried toggling them all on/off/on, but they're still not working at all? List of gestures not working: - Launch Pad (4 Finger pinch) - Reveal Desktop (4 Finger spread) - Mission Control (4 Fingers Up) - App Expose (4 Fingers Down) - Switch Spaces (4 Finger Swipe Left/Right) - Notification Center (3 Fingers from right edge.) Gestures that are working: - Scrolling (2 Finger drag) - Select/Drag (3 Finger drag) - Look Up (3 Finger tap) - Secondary Click (2 finger tap) Thoughts? (Oh, and I'm using a Magic Trackpad.) Edit: Resolved with a simple restart... no idea what caused my gestures to suddenly stop working like that, though.
