title: Refactor rename broken in Intellij IDEA
body: <p>Somehow, I managed to break my refactoring capabilities in Intellij IDEA 12. I have somehow disabled it for my project. Renaming a member through <kbd>Shift</kbd>+<kbd>F6</kbd> doesn't work. The inline edit box is not drawn, nothing happens.</p>
  
  <p>I know of the refactoring settings in <code>Settings -&gt; Editor</code>, <code>Enable in-place mode</code> and <code>Preselect old name</code> are both checked.</p>
  
  <p>It has to be some kind of project setting. I checked by creating a test project, adding some member and renaming it, which works perfectly.</p>
  
  <p>What setting am I looking for? Or could my project be broken?</p>
