I recently bought a logitech rumplepad 2 gamepad for my computer so I could get a similar experience to my PS2 controller, but the gamepad's response is a little messed up. Whenever I hit a button or move the joystick, it does that action twice. For example if I tap the fire button, it fires once, then hesitates a half a second, then fires again. Same thing happens on the joystick. Is there some way to disable this, or is it the gamepad's malfunction? It makes playing any game a real pain.

btw I have windows vista ultimate with SP1, and i have the logitech gaming software version 5.02
