This only happens both in the Unity 3D Engine and the Unity Web Player. I believe my Madcatz Xbox 360 controller messed up the WASD and arrow keys. Now the WASD and arrow keys are sticking virtually Up and Right (Also W and S). This will not stop no matter what keyboard. I tried unplugging and re-plugging the controller and still no luck.
This still happens even when both the controller and the keyboard are both unplugged!
I know it is my controller because I am able to control the WASD and arrow keys with the right joystick.
