title: How should I make a system-wide dialog for Windows 8?
body: <p>I have an application that presents a dialog to the user. This dialog must be dealt with within a few seconds (it is to allow or deny a connection to the computer). </p>
  
  <p>In Windows 7 this is not a problem: I present a dialog (without stealing focus) that displays on top of all other windows. However in Windows 8, this dialog is only visible on the desktop. If the user is on the Metro Start Screen, or in another app, the dialog is invisible. </p>
