Anyone's 2 finger scrolling just stop working

[RDAR]

My 2 finger scrolling does not work for anything. Safari, Chrome, Finder anything where I can scroll does not work. I have to put my macbook to sleep and reopen it for everything to work again.

At least twice that happened to me, but only in the Finder. Two-finger scrolling works fine everywhere else.

(EDIT) Ahhh....if I pull down "Force Quit" and then re-launch Finder, the two-finger scrolling works again.
