I have a Naga X mouse and in the past week the key bindings that i’ve been using for years have kinda failed.  I bind the pad on the side of the mouse to the Num Pad keys on my keyboard for a game, and in the past week for whatever reason whatever i bind those side pad keys to they will press the button bound and the original button, so for example i want to hit Num 1 and i end up hitting Num 1, 1.  Or if i were to bind it to R it would hit R, 1.  i thought my mouse broke because somethings rattling around in it and the lights have been going crazy for a while, so i bought a NAGA  V2 hyperspeed and it does the exact same thing.
