Something has changed the behavior of some of the keys on my keyboard. When I press the ALT key it closes what ever program is open to close. This should only happen with ALT + F4. If I try to type something in this text box while Microsoft Flight Simulator FSX is running it brings up a Java Script box and types there. In FSX my throttles stay at max. The F1 key which is supposed to bring the throttles to idle doesn't work unless I hold it down. When I release it the throttles return to max. I can't idle the throttle using the mouse on the throttle control either, it jumps back and forth. I tried a different keyboard but got the same results so its software related.
