Briefing Time B-25 FSX shut down issue

When closing a flight from any of the Briefing Time paint jobs and using end flight button in FSX the FSX screen moves to the bottom right of the screen and unable to close FSX unless using Task Manger, End Task. Installed the FSX Basic Compatibility Update also. After using Task Manager, End Task, Windows looks for a problem and reopens FSX and can close FSX normally. OS Windows 7 64 professional. No other aircraft causes this issue when closing a flight.
