trackpad gestures
Every so often, my trackpad gestures will just stop working, can't swipe between windows or summon launch pad. Not sure what provokes this, but when I restart the computer everything is back to normal. I would rather not have to restart my computer all of the time to fix it, is there something else I can do?
Thanks
