title: TEE 2012 does not check out files automatically
body: <p>I have TFS Server 2012 SP1.
  Eclipse 3.6.2 (Helios Service Release 2).
  TEE 11.0.0.201211191425</p>
  
  <p>I see a complete team menu, I can check-out and check-in files manually.
  However if I just start editing a file it will not be checked out automatically :( as it did with 2010 before updates.</p>
  
  <p>I have tried to change settings to "Display progress while checking out" and "Prompt before checking out" - no effect. </p>
  
  <p>"Detect changes..." functionality does not work either.</p>
  
  <p>Only if I close the project and then open it again, the modified file will be checked out automatically (only once).</p>
  
  <p><strong>wtf???</strong></p>
  
  <p><strong>UPDATE:</strong>
  The modified file will be checked out automatically also if I manually check-out/check-in another file in the same project.</p>
