i forget if there's already a topic here, but i'm sure everyone's had this problem, even if yyou use a game controller. at some point in almost every song, you'll notice that AS will completely ignore the mouse input, thus(if you're using Mono, Mono Pro, or Ninja Mono), will leave you roaring/screaming at your computer, and/or beating the crap out of it. also, if you're using an IBM TrackPoint or a touch pad, you'll notice that you'll have to make Mono Pro jump, or just take your finger away from the pad/'Point and quickly put it back, and that usually fixes the problem, but with wired and wireless mice, AudioSurf will basically shoot you the finger as if saying "i'm done, fuck you."
