well this sucks.
Firefox 1.5 seems to have broken my forward and back mouse gestures from StrokeIt.
(Yes, I know it sounds dirty, stuff it.)
StrokeIt is the one thing keeping me from full-time Linux use at home, it's just too good to give up!
*goes grumpily looking for a solution*
Feh, I ended up just adding mozilla windows to the Browser gesture set in StrokeIt.
Wonder what they changed to make that break...
