I had BetterTouchTool installed on SL, and when I moved to Lion it started messing gestures up so I've learned to live without it. Now I've lost three-finger navigation gestures after every reboot, I have to start BTT and then quit it to get my three-finger gestures back. I use four fingers for desktops and Mission Control and 3 fingers for navigation. I don't want BTT anymore but I have to keep it because of that stupid bug, and if I drop it in the trash then I have NO WAY to restore three-finger gestures. Does anyone know how to get to the bottom of this so I can undo whatever it is BTT did and get my three finger navigation gestures back?..
