So I am far from techno-tarded but this is driving me crazy and maybe you guys can help. I have lion on both my MBP and my Mac Mini. On the MBP, I can use 4 Finger Gesture left or right to move to different desktops or to the dashboard. I like this feature a lot and use it often. I have the Magic Trackpad on the Mac Mini, but this feature DOES NOT work and it is killing me. Why does it work on the MBP but not the mini? I have no clue why I can get 4 finger gestures up and down which work perfectly fine with Mission Control, but left and right don't allow me to "shift desktops" or get to the dashboard. Am I missing some type of setting or something? I searched but did not find this problem so thought I would ask the experts.
