Ok. Figured out it was something to do with the game controller installed by Windows 7, however even after I disabled it I can't set the control buttons on the cab?????
I just installed Windows 7 SP1 and now I can't map my Joystick settings. The window opens for a split second and sets the button to left. Worked fine on XP but couldn't load .Net 4.6 so upgraded. Any ideas?
