title: a script on this page is causing ie to run slowly
body: <p>The problem is in the title - IE is misbehaving and is saying that there is a script running slowly - FF and Chrome don't have this problem.</p>
  
  <p>How can I find the problem . .there's a lot of JS on that page. Checking by hand is not a good ideea</p>
  
  <p><strong>EDIT :</strong> It's a page from a project i'm working on... but I need a tool to find the problem.</p>
  
  <p><strong>End :</strong> It turned out to be the UpdatePanel - somehow it would get "confused" and would take too long to process something. I just threw it out the window - will only use JQuery from now on :D.</p>
  
  <p>And I'm selecting Remy Sharp's answere because I really didn't know about the tool and it seems pretty cool.</p>
