What does the obscure javascript error b(e.target).zIndex is not a function mean?
<p>To give more information I am using the modular form here:</p>

<p><a href="http://jqueryui.com/demos/dialog/#modal-form" rel="nofollow">http://jqueryui.com/demos/dialog/#modal-form</a></p>

<pre><code>`b(e.target).zIndex` is not a function  
[Break on this error] `(function(a){a.widget("ui.mouse",{opti...is._unrotate}return this}})})(jQuery);`  
/js/jquery-ui.min.js
</code></pre>

<p>I also seem to be getting the error "Too much recursion"</p>

<pre><code>too much recursion  
[Break on this error] `3||a.nodeType===8)){if(a.setInterval&amp;&amp;...this.special[o]||{};if(!t){t=e[o]={};`  
https://my.dev.peer1.com/js/jquery/jquery-1.4.min.js
</code></pre>

<p>I know its not much to go on but I was hoping someone might have experience with similar issues.</p>
