When hover too fast between elements, double elements show
<p>When I hover between elements very quickly, two or more elements will show. If move slowly, it works perfect. Here's the code:</p>

<pre><code>$("#services_menu a").hover(function(e) {
  var id = this.hash;
    $("#services_description div:visible").not(id).fadeOut('fast', function(){
    $(id).fadeIn();
  });
  e.preventDefault();
});
$("#services_description div:not(#agency_leasing)").hide();
</code></pre>

<p>How do I fix this? Thanks.</p>
