title: Eclipse <ctrl>-click Hyperlink Not Working
body: <p>I'm running Eclipse Kepler, and for some reason, the ctrl-click hyperlink feature isn't working in one particular workspace.</p>
  
  <p>I've looked at <a href="https://stackoverflow.com/questions/4387450/disable-eclipse-ctrl-click">this question</a>, and the correct box is checked.  The code is compiling cleanly.  What else could be causing this behavior?  It's a very useful feature, and I'd like it back.</p>
  
  <p>(And this may well be related -- "Mark Occurrences" isn't working in that workspace either, even thought the "Toggle Mark Occurrences" button is pressed.)</p>
