title: Eclipse IDE lost popup menu suggestions
body: <p>I've seem to have lost the ability in my Eclipse to auto-correct errors in my source code lines.</p>
  
  <p>For example, a line like this:</p>
  
  <pre><code>Date date = new Date();
  </code></pre>
  
  <p>has red jagged lines beneath the Date() part. Previously I could mouse hover over it see a popup menu of options to fix it. Now I all I ever get is a popup with the text "Cannot resolve to a type".</p>
  
  <p>The only change I can think of that I've made and I don't know if it has anything to do with this problem, is that I started editing my .java files with an outside editor. Then focusing back into Eclipse I get a popup saying the source has changed and do I want to update so I say OK.</p>
  
  <p>Sometimes I will edit inside Eclipse and sometimes i will edit the source outside of Eclipse. I'm not sure if this is a bad practice or not?</p>
