On any Unity browser game or on the Unity game I am building, the left+down arrow keys are stuck virtually. It even happens with the keyboard unplugged! The keyboard uses a USB. I am using a Systemax Pc. This started happening a few weeks ago.
Bump
I have waited for a week now and still no answer. It seems to be Madcatz Xbox 360 controller doing something because I can control the arrow keys with the right joystick. And no, unplugging the controller does not work.
