   They are generally useful for prompt dialogs or other things where it's   
   natural to suspend interaction with the primary window.  And there are   
   many cases where there's no particular need to have a non-modal dialog   
   but it would be extra work to properly manage one (e.g. working out   
   how to handle messages when a dialog is open).
