Reset

I tried to right-click for a contextual menu this morning, and it didn't work. When I went in to System Preferences, it turned out that my Mighty Mouse had somehow been reset so that right-click and left-click did the same thing. I've fixed it, but it's something to look out for, lest it happen again.

I just noticed that the little wheel scrolls horizontally as well as vertically. That's pretty cool.
