How to reset Logitech mouse's back/forward buttons? I've been using my Logitech Anywhere MX with my Mac succesfully for a couple of months, but suddenly last week the functionality of the back/forward buttons changed from navigating to previous/next page in history to switching to next/previous tab in Chrome. How can I restore the previous functionality?

I've already checked the Logitech Control Center, and there the buttons are still defined as back and forward.

Note: If I remember correctly, the buttons have never worked in Finder.
As I mentioned in the comments, I found no other solution except changing the buttons to send the corresponding keystrokes. Fortunately, this works fine in almost every app I frequently use, including Finder.

The keystrokes I used were command+option+8 for back and command+option+9 for forward. Note that this is on a Finnish keyboard layout.
