I'm having a problem with displaying the exception window when the app throws an exception. The code is in MainEntry.cs.

                // Log any unhandled exceptions
                appWrapper.Application.DispatcherUnhandledException += delegate(object sender, DispatcherUnhandledExceptionEventArgs e)
                {
                    // Write the error to the application log
                    mmAppBase.Log.WriteException(e.Exception);

                    // Display the Exception form
                    var ExceptionWindow = new mmExceptionWindow(e.Exception.Message, e.Exception.StackTrace);
                    ExceptionWindow.ShowDialog();
                };

The dialog window is displayed, but is completely empty; no text, not buttons...nothing. Anybody know what's happening here?
