Is this bug going to be addressed in 10.9.2?
Possibly unrelated but three-finger swipe to bring up Mission Control and App Expose has been very annoying since around Mountain Lion and continuing into Mavericks (10.9.2).
The annoyance - three-finger swipe up/down for Mission Control and App Expose do not work after a restart UNTIL you go into the Trackpad preferences and deselect and then reselect either one of the checkboxes.
Very annoying. Luckily I do not have to restart very often.
Oh and three-finger swipe left/right to change pages and go back/forward in browsers work fine for me (no BTT).
For information (and comparison) purposes, here are my settings for the Trackpad prefpane:
Swipe between pages - Swipe with two or three fingers
Swipe between full-screen apps - Swipe left or right with four fingers
Notification Center - Swipe left from the right edge with two fingers
Mission Control - Swipe up with three fingers
App Expose - swipe down with three fingers
Launchpad - not enabled
Show Desktop - Spread with thumb and three fingers
And one more setting [the person(s) who moved this from the Trackpad prefpane should be shot, hung and quartered] :-
Accessibility prefpane > Mouse & Trackpad > Trackpad Options ... > Turn on Enable dragging with Drag Lock - this is the old double-tap-and-hold-on-second-tap to move/drag windows/items around or to do selections.
I tried the three-finger-drag method and found it very cumbersome especially when working within Excel trying to select multiple cells - moving one finger is more precise than trying to coordinate three fingers only to have one finger drop off the edge and repositioning.
