title: jQuery $(document).ready() failing in IE6
body: <p>I have the following code:</p>
  
  <pre><code>// Creates a timer to check for elements popping into the dom            
  timer = setInterval(function ()
  {          
      for (p in pixelTypes)
      {                             
          checkElems(pixelTypes[p]);
      }                            
  }, 10);
  
  // Add Document finished callback.
  $(document).ready(function ()
  {         
      // Document is loaded, so stop trying to find new pixels
      clearInterval(timer); 
  });       
  </code></pre>
  
  <p>In Firefox, it works great, but in IE6, I get a "Object Expected" error on the $(document).ready line.</p>
  
  <p>I can't figure out what would cause IE6 to not recognize it, jquery is fully loaded by this point.</p>
  
  <p>Is this a known issue?</p>
