title: jQuery UI sortable tolerance
body: <p>I'm having some trouble getting smooth operation of jQuery UI sortables.</p>
  
  <p>The tolerance I set doesn't always work correctly - for example, if I set it to 'pointer', sometimes I could have the object almost on top of another (mouse incl.) and it won't reorder. Some time I have to jiggle the object to get it to reorder.</p>
  
  <p>Is there anything that is required to work correctly or anything that can cause it to break? (margins, float, certain elements, absolute positioned elements, etc?)</p>
  
  <p>The code I have is basically something like this (anchor as abs. positioned):</p>
  
  <pre><code>&lt;div span="span-12 prepend-top last"&gt;
      &lt;ul id="fileupload-images" class="ui-sortable"&gt;
          &lt;li class="image span-3" id="38b22e1c130d9c33fafb20e7ac16c038"&gt;
              &lt;img class="thumb span-3 last" src="/uploads/3/8/b/38b22e1c130d9c33fafb20e7ac16c038/38b22e1c130d9c33fafb20e7ac16c038.jpg"&gt;
              &lt;a href="#" class="zoom"&gt;&lt;/a&gt;
              &lt;a href="#" class="remove"&gt;&lt;/a&gt;
          &lt;/li&gt;
      &lt;/ul&gt;
  &lt;/div&gt;
  </code></pre>
