title: Windows Store App shows black screen
body: <p>I have a problem with my Windows Store App Car Buddy. Microsoft Support contacted me about a problem with my app, that it shows only a black screen instead of actual content. I am unable to reproduce the error, although I tried on several computers that are available to me.</p>
  
  <p>But the problem has been also brought to my attention by users, and honestly I have no idea what is the reason. There are no errors, the app does not crash, apparently while in black screen users can still access Settings Charm and pages that are available from there.</p>
  
  <p>Can you help? If you need additional information just ask. I am clueless atm...</p>
  
  <p><strong>UPDATE 31.05.2013: It seems that while navigating from ExtendedSplashScreen to first page, the Frame.Navigate method returns false, and no exception is thrown. Any ideas how to debug this? Or force the exception to show?</strong></p>
