I have tried to save an aircraft type in my aircraft library on my mac pc but the message I get "unhanded exception has occurred in your application.  If you click Continue, the application will ignore this error and attempt to continue.  If you click Quilt, the application will close immediately.
Value was either to large or too small for a Decimal"
But even if I click continue I still can not save any information.
Any help would be very much appreciated.
