title: Visual Studio 2015 RTM Find in Files dialog broken
body: <p>The <code>Find in Files</code> and <code>Replace in Files</code> dialogs will not open.  Neither through shortcuts nor through the menu items.  </p>
  
  <p>What could be the problem, how could I debug this?</p>
  
  <p><strong>Update:</strong>  </p>
  
  <p>The same dialogs are broken on my copy of Visual Studio 2013 as well.  This started happening after uninstalling VS2015 RC and installing VS2015 RTM.</p>
