The main window has a button that opens a dialog. The dialog has a button that opens another dialog. The second dialog has a button that closes the dialog. The second dialog has a button that closes the second dialog and returns the data to the first dialog. The first dialog has a button that closes the first dialog and returns the data to the main window. The main window has a button that closes the application. All of this works fine. The problem is that when I close the application, the main window is not properly disposed, so the application does not close. I have tried calling Close() in the CloseCommandExecute() method of the main window, but this does not work. I have also tried calling Close() in the OnClosing() method of the main window, but this does not work either. I have also tried calling Close() in the OnClosed() method of the main window, but this does not work either. I have also tried calling Close() in the OnClosing() method of the first dialog, but this does not work either.
