Controller bug

I'm not sure if this is the right place to report this, but I cannot find a bug reports forum for STK anywhere.
My keyboard keys are: left=z, right=x, forward=f, back=c.
I plugged in a USB game controller. That worked fine. Seriously good work there guys. Sadly, as soon as I use it, the "f" and "z" keys stop working in game mode and single player mode. I have to drive backwards and turn right by doing a full circle.
All keys work fine in multiplayer mode even when the bug is seen in the other modes.
Other keys may also have stopped working, but it's kinda hard to tell.
