So here's the problem: Whenever I press the "c" key, it gets used twice. This has been going on, but now I'm getting tired of it. What I've already tried: I've left it unplugged overnight; and I have looked under the key to see if anything's stuck (and there wasn't). I will try any and all solutions and respond to them. P.S. This happens whenever I use the key, not just in games.
