Ever sicne I have installed FS2004, my kneeboard appears while in flight causing my landing gear and flaps to deploy. I often fly transcontinental flight that end up crashing... Am I the only one with this problem? What should I do?
Check your keyboard assignments. I've never heard of the kneeboard just "popping up", but it may be something to do with a keyswitch.
Or it MIGHT be a virus or spyware/adware. The checklists and kneeboard documents for the default aircraft are all in HTML format, so there may be something confusing them with net site links or something.
