So I called Apple Support about my Mighty Mouse issues. They figured it was the mouse itself, so they sent me a new one. Plugged it in and....problems remain. Basically, right clicking doesn't really work too well at all, it only works on the extreme right side above the side button. As for the side buttons, touching the mouse anywhere sets them off. So I'll rest my hand on the mouse, and expose or whatever is going nuts, with the speaker'd clicking sound. The problem isn't the Mouse itself. I plugged it into 2 different PCs, and it worked normally. Right clicking was great, no clicking sounds just from touching the mouse. This is with the original mouse, and the replacement that Apple sent me. Now what? The problem is either with my iMac, or OS X. I don't want to have to re-install the OS, but I mean, I want a mouse that works. Is there a way just to reinstall the mouse itself, or some utility? (And yes, I have the mouse set up fine in System Preferences) Any help would be great! Thanks!
