Just installed FSX on a new Windows 7 machine, and we've run into quite a problem.
Whenever we run 'Kiosk Mode', FSX will crash after about a minute of flight time, and display the "A fatal error has occurred" message box. FSX seems to run just fine by itself - no crashes so far.
We've placed a new "UIAutomationCore.dll" file in the FSX folder, and we've tried compatibility mode - no luck so far.
I've attached the error that shows up in the application log:
Any thoughts?
