My function slides a div called slidebar down & then back up without user interaction. I would like returning visitors to not see the div slide. I have a cookie that worked with my scriptaculous sliding div, that doesn’t work with my much smoother JQuery one.

My function

```auto

 
$(document).ready(function() { 
        initSlideboxes(); 
 
        function initSlideboxes() 
 
{ 
$('#slidebar').slideDown("normal"); 
setTimeout(function() 
{ 
  $('#slidebar').slideUp(3000); 
 
}, 5000); 
 
 
        $('#slidebartrigger').click(function(){$ 
('#slidebar').slideToggle(); }); 
 

```

A JQuery cookie I found on the jquery group
