The issue is basically as described in the thread title. Out of nowhere, my Magic Mouse doesn't seem to recognize left and right 2-finger swipes (forward/back in browser, and I've also used Better Touch Tool to make it change songs in iTunes). The only change I've made was to install the drivers for a Digidesign MBox 2 (audio/MIDI interface for recording). I checked my mouse preferences, and the box for the 2-finger swipe is checked. I've turned the mouse off and back on, restarted BTT, restarted the computer, and pretty much everything else I can think of. Does anyone have any ideas, or has anyone else experienced this issue? Is there any chance the MBox could have some effect on this? I don't see why it would, but who knows?
