OK, no harm done. Just to let you know though, I wasn't actually trying to crash anything. I just pressed the function button and the program crashed. I think you experts don't realize that there are many of us who are using this program for the first time. I just pushed a button, that's all. I think what you guys have accomplished is wonderful. The simulator is very complex and realistic and I'm enjoying flying the aircraft. Whenever the program crashes though, there must be a reason for it and I want to report it so you can have a look. Happy flying.
