title: Nodes timing out in umbraco back-end
body: <p>I'm having an issue with an umbraco site of mine: For some reason some of the nodes are timing out when I try to click on them in the back-end of the site.</p>
  
  <p>The front-end works fine and there aren't any slowdown issues there, however I'm unable to edit these same nodes in the back-end as the system seems to just hang. This is making it incredibly difficult to debug as I have no idea what properties are actually causing the problems here. What's strange is I can create a node of the same document type and enter in some dummy values and that works fine, yet I can't seem to edit the existing nodes.</p>
  
  <p>I've tried republishing the entire site, republishing the individual nodes, deleting the umbraco.config file and nothing has worked up to this point.</p>
  
  <p>What's also interesting is that if I close down the browser the system seems to stop hanging and I can log in and try again.</p>
  
  <p>Has anyone encountered this before or know where to begin?</p>
  
  <p>Thanks</p>
