Hi, I have strange issue with my (Microsoft Digital Media Pro) Keyboard in FSX. While F1 always works to idle throttle, none of the other Funtion keys (F2-F12) works, even though in FSX control settings

I use the same keyboard. I don't have that problem at all. My guess is that you've activated/deactivated the F LOCK button on the top right, as this switches between the functions and the media buttons for the F keys (look for the LED light that has an F with a box around it). If that's not the case, then you might have to go into the keyboard wizard in Windows and make sure you didn't accidentally re-program the F keys to something else. Beyond that, I don't know, your keyboard should work.Jeff ShylukAssistant managing EditorSenior Staff ReviewerAVSIM
