title: iPhone 5 (4") bottom toolbar not responding
body: <p>I'm trying to modify an app to work with the new iPhone 5, 4" screen.
  I've added the new launch image, "Default-568h@2x.png".
  After that everything seemed good. Middle portion of my views is resizing ok.</p>
  
  <p>However I've noticed that in a view where I have a bottom toolbar, the buttons on the toolbar are unresponsive. It looks ok, but tapping buttons does nothing. Same code run in simulator with 3.5" screen works fine.</p>
  
  <p>Any ideas?</p>
  
  <p>This view is within a navigation controller. It consists of a table view and toolbar. The tableview is set to resize height.</p>
