title: How to ignore certain script files / lines when debugging?
body: <p>I'm trying to debug some JavaScript, I want to find out what code gets executed when I hover over a certain div element (I've got no idea which bit of code, because there's no direct 'onmouseover' - I think there's a jQuery selector in place somewhere?).</p>
  
  <p>Usually I'd use the "Break All" / "Break On Next" facility provided by Developer Tools / Firebug, but my problem is that other code (tickers, mouse movement listeners etc.) immediately gets caught instead.</p>
  
  <p>What I'd like to do is tell the debugger to ignore certain JavaScript files or individual lines, so that it won't stop on code I'm not interested in or have ruled out. Is there any way to achieve that in IE (<em>spit, spit!</em>) - or could you suggest a better approach?</p>
