Thanks for the advice! My joystick suddenly stopped working in FSX. I have FSX installed from Steam. I tried the fix in Steam (Steam must be started from the app tray and not from the desktop icon) described in a previous post, and Steam could see the joystick. After unchecking all the boxes the Steam screen went black, and says no controller can be detected. But after a couple more starts and stops of Steam and FSX, it finally detected the joystick with all the General Controller boxes unchecked. So after stopping and restarting Steam several times, FS finally sees the joystick.
