I got a Wireless Mighty Mouse for Christmas, and I've paired it with my MBP. I've assigned the right button as the secondary button in >System Preferences>Keyboard and Mouse>Mouse. But for some reason, it will only acts as the secondary button for a couple of minutes after booting, and then it just goes back to acting as the primary button. System Preferences still show that it's the secondary button, but it's not functioning like it. It's pretty frustrating. Has anyone had this issue with their Mighty Mouse or know how I can fix it? Thanks!
EDIT: Nevermind, I just searched the Apple Discussion boards for this and found this thread. Bummer.
