Logitech mouse buttons.

I logged in today to find that the thumb side buttons on my Logitech mouse no longer seem to work properly. The first mouse I tried was a Logitech MX400, and the side buttons seemed to rotate the camera left and right and after using them, all the rest of the buttons stopped working properly. I thought that maybe it was the mouse so I plugged in my Logitech MX Revolution and that one had the same problem. I tried resetting my bind files in COH and checked to make sure the preferences were correct for the mouse on my computer but nothing seems to help.
I was wondering if anyone else was having this problem. I'm running OS X 10.6.8.
