FSX Exits problem

Hi all,
I'm Kai from holland and I've a question.
When i create a free flight in FSX (choose plane, country, airfield etc.) and I save it, Im getting problems with the exits of the plane and its really anoing
. If I want to open the exit nothing goes wrong but when its opened it directly closes itself :-?, does anybody has the same problem and do you know the answer to this?
regards
Kai
