// 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?
