Now I'm having this issue as well but the bloody bugger is being all bloody buggery!!!!
I'm sick of Apple's little quirks like this. They accumulate over time making for a bad experience and I'm sick of losing so much hair over this kind of crap!
I payed over $60 for this damn mouse and they still managed to ef'k THAT up?! IT'S A MOUSE!!!
I'm sick of this, if I can't get it fixed I'm gonna chunk it back to the Apple store from which it came, and not through the door!
So...I deleted all my bluetooth prefs, is there a way to obliterate all the rewritable data on the mouse?
