I am using fsx on windows 7. Everything works fine except when I try to load a certain aircraft .For example when I try to load Fairchild sa227ac metro III. Most of the time it stops fsx. I can load any other aircraft ok. I then load another aircraft and when loaded I change aircraft to the Metro III and all is ok. It will fly ok. But if I want to save the flight it saves ok , and when I want to fly the saved flight it stops fsx every time. If before I save it I change to another aircraft then save. I can fly that saved flight. I then change aircraft to the Metro and carry on flying. It seems that that particular aircraft is not completely compatible with fsx. I don't know. Does anyone have any ideas. Thanks Ralph

While I have not encountered this problem, I understand that it is common with some addon aircraft for FSX. In fact, with some payware aircraft it is recommended that a default aircraft be loaded and then changed to the payware aircraft.
