title: Flash Builder (ecplise) syntax coloring not working
body: <p>A few weeks ago syntax coloring stopped working for the odd file. Or halfway down a file. Now its becomming increasingly the norm.</p>
  
  <p>I've cleaned the project, pruned out a whole heap of closed projects, but it hasnt improved things.</p>
  
  <p>What would Stack Overflow suggest?</p>
