title: ReSharper 5.1 can't navigate to a type from anywhere
body: <p>I'm running Visual Studio 2010 (10.0.40219.1 SP1Rel) with ReSharper 5.1 (5.1.3000.12).  Recently, it seems as though ReSharper has completely lost the ability to navigate to a type.  </p>
  
  <p>Here are some actions I can take in the UI that now do nothing:</p>
  
  <ol>
  <li><p>Right-click on type name in code
  editor and select "Go To
  Declaration"</p></li>
  <li><p>Right-click on type name in code
  editor and select "Go To
  Implementation"</p></li>
  <li><p>R# "Go to type" (Ctrl-T)</p></li>
  <li>In the R# "Find Results" window, double-clicking a type</li>
  </ol>
  
  <p>Here are some actions that still work:</p>
  
  <ol>
  <li>Double-clicking an item in Solution Explorer</li>
  <li>Opening a file from VS Command Window</li>
  </ol>
  
  <p>I've completely uninstalled Visual Studio, then reinstalled it with SP1, and ReSharper 5.1, and I still have the same problem.</p>
  
  <p>I'm assuming there's some kind of configuration open that I've done that is disabling the ability to navigate to a type with ReSharper, I just can't figure out what it is.</p>
  
  <p>Any advice would be much appreciated.</p>
