[jQuery] slideDown and slideUp are jerky

[JohnieKarr]

Hello,

I have a site: www.lovinggodlovingyouonline.com that the menu is jerky
in IE6 & 7 on xp.  FF is really smooth.

I would prefer onmouseover, but I changed my code to onmouseclick to
help remedy the problem, but it did not work.  Does anyone have any
suggestions regarding this?  My jquery code is below:

<script type="text/javascript" src="jquery-1.2.3.js"></script>
  <script type="text/javascript" src="jquery.blockUI.js?v2.04"></
script>
  <script type="text/javascript" src="bubble.js"></script>
  <script type="text/javascript" src="jquery.ifixpng.js"></script>
  <script type="text/javascript">

   // unblock when ajax activity stops
   $().ajaxStop($.unblockUI);

   $(document).ready(function() {
    jQuery('#GetlogIn').click(function() {
     jQuery.blockUI({ message: $('#loginForm') });
     });

   $('#cancelLogIn').click($.unblockUI);

   $('[EMAIL PROTECTED]').ifixpng();

   $("dd:not(:first)").hide();
    $("dt a").click(function(){
        $("dd:visible").slideUp("slow");
        $(this).parent().next().slideDown("slow");
        return false;
    });

   });
  </script>

I included all the scripts that I am using if that helps.

Thanks,
