I'm having issues with my bright new mighty mouse. The right click only seems to work when it wants to. I've tried my hand in all different positions, sometimes I get a run of it working, much of the time it just counts as a left click. Left click works fine by the way. Have I missed something in mouse settings? I made right click button 2. Is this a problem with mighty mouses? Is this one faulty? If it's faulty, I bought it online, can I take it into apple store and swap it? Thanks.
