Is it normal for the game to crash every 2nd flight or so?

[Sinopia]

I use the FSX Steam edition and i've downloaded a uiautomationcore.dll and put it in my FSX Main directory and that didnt make a difference sadly. What i currently do is every time i complete a Fspassengers flight i close and start the game again because if i click the menu after finishing the flight it Will crash out of 25 tries it crashed 23 times (trying a second flight right after that is)
