How do I get three finger gestures working again in Twitter for Mac after installing Lion? After installing Lion, three finger gestures no longer work in the Twitter for Mac app.  (I've gotten used to swiping left with three fingers to go "back" after—for example—clicking on a person's avatar to see their timeline.)  In the Trackpad System Preferences panel I've disabled three finger drag, and changed "Swipe between full-screen apps", "Mission Control" and "App Exposé" to four fingers to try to eliminate conflicts.  But the three finger swipe still doesn't work in Twitter.

Has anyone been able to re-enable three finger gestures in Twitter for Mac?  How did you do it?
This annoyed me too, and it doesn't seem the solution is entirely satisfying — we'll just have to hope that Twitter for Mac gets updated soon to be better compatible with Lion.

If you have "Swipe between pages" set to "Swipe left or right with three fingers" or "Swipe with two or three fingers", then left/right three-finger swipe gestures will work in Twitter.

If you have Mission Control &amp; App Exposé set to "Swipe up/down with three fingers", then you can hold ⌥ Option to use up/down three-finger swipe gestures with Twitter. (I'm not sure why, but if you have these set to 4-finger swipes, it doesn't seem 3-finger swipes work at all in Twitter.)
