title: Visual Studio 2012 - Intellisense sometimes disappearing / broken
body: <p>My colleagues and I are using VS2012 for some weeks now. Sometimes after working several hours the intellisense is broken. After closing all open tabs it works again.</p>
  
  <p>Are there more people out there having the same problem? It can't be an extension problem because I have the same problem at home. Maybe there is a workaround for this?</p>
