title: jQuery 1.5.1 vs. Prototype causes Unresponsive Script in FireFox
body: <p>After upgrading to jQuery 1.5.1, I get the Unresponsive Script warning in FireFox.</p>
  
  <p>Nothing else was changed, only jQuery upgrade from 1.4.2 to 1.5.1. If I debug the script, and see the stacktrace I can see that the code that causes the unresponsive script is quite simple:</p>
  
  <pre><code>$("div.activityItems[gid='-1']").children().attr("disabled", "disabled")
  </code></pre>
  
  <p>Has anyone else experienced similar issues, in regard to jQuery 1.5.1?</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>I've localized the conflict to be between JQuery 1.5.1 and Prototype. Upgrading Prototype to v. 1.7 results in obvious conflicts:</p>
  
  <pre><code>$(document.body).keydown is not a function
  $.fn is undefined
  </code></pre>
  
  <p>Any ideas for a workaround?</p>
