How do I make a dialog block the whole application, so the user is forced to answer it?
This is called a modal dialog. Modal dialogs in general are unpleasant things, since they force a question upon the user. Ideally, the application should offer choices to the user non-obtrusively, instead of making demands upon him. Having said that, there are times where a modal dialog is either necessary or an easy solution. Any window of the application can be set as modal; this will force it to be dismissed before the normal flow of the application is restored. FIXME: window.hide() removes modality?
