Closing the application should restore the Start dialog only when the application is fully stopped.

Right now, if you stop an application, the Start dialog is shown immediately, as the red dot is still blinking. It should instead disable the application view, and show the start dialog again only when the application is really stopped.

Should we disable the start button the same way we do when the application is starting or should we just not display the form ?
