Is there an unhandled exception handler in Inventor?

[gene.buckle]

In "normal" .Net, I can catch unhandled exceptions via the UnhandledException handler in the application domain.  I've tried a very simple example (swiped right from the MS help files..) and it's not working.  I'm assuming that it's because Inventor has already grabbed this and its handler is superseding the one I'm trying to create.

Here's the example I'm trying: (External Rule)

Sub Main()
      Dim currentDomain As AppDomain = AppDomain.CurrentDomain
      AddHandler currentDomain.UnhandledException, AddressOf MyHandler
      
      Try
         Throw New Exception("1")
      Catch e As Exception
         Logger.Info("Catch clause caught : {0}", e.Message)
      End Try
      
      Throw New Exception("2")
   End Sub
   
   Sub MyHandler(sender As Object, args As UnhandledExceptionEventArgs)
      Dim e As Exception = DirectCast(args.ExceptionObject, Exception)
      Logger.Info("MyHandler caught : {0}", e.Message)
      Logger.Info("Runtime terminating: {0}", args.IsTerminating)
   End Sub

The example above should execute MyHandler when the second exception is thrown.  Instead, it appears to be trapped by Inventor:

The reason I'm doing this is that I'd like to be able to grab a screen shot and attach that to a support ticket.  This will both decrease the reporting requirements of my users and increase the information I've got available when something goes pear shaped on them.

Thanks folks!
