Whenever I press Caps Lock in my web browser, it functions as the 'back' button in the browser. It does the Caps Lock as well, but it also jumps back a page. I have no idea what's causing this; it just started to act up.
Anybody know what may be causing this and what I can do about it?
ETA: It's doing all sorts of other weird things, too. Like when I press CTRL, the calculator pops up. And when I press ALT, Outlook starts up.
