I just downloaded and installed STK. I was having so much fun I decided to dust off an old PSX controller and plug it in (Windows Vista). STK recognized the controller after I restarted it. I tried playing with the default controls, but I didn't like the button choices so I went into setup to customize them. Upon returning to the game screen I find I still have the same default controls. I've even tried restarting STK with no luck.
Any ideas? Thanks in advance!
