I have tried two FC3 aircraft and they work fine except the F-15C. I cannot do anything in that aircraft. Keyboard does not work at all, Track-IR does not work, but joystick input works. Escape does not work so I have to use my mouse to click on the start bar in order to get keyboard responses. Alt+F4 does nothing. Again this is only with the F-15C. Su-25T works fine. Ediit: Just realized Su25T is a World aircraft. So FC3 isn't working for me. Keyboard inputs do not work at all. Every other module works fine.
