Jquery and Protected Mode in IE8

Jquery and Protected Mode in IE8

Hello,
 
I have the following code:
 
function addToCart(a){
 var uri = '?ajaxform=cart~~task=add~~id=' + a + '&UTI=' + getUTI();
 $('#cart_details').fadeOut();
 $.ajax({
  type: "GET",
  url: uri,
  success: function(txt){
   // Hide the Beta Logo if it's there
   //try{$('#beta_logo').fadeOut();}catch(e){}
   
   // Display the Cart Results for the User to see
   $('#cart_details').html(txt);
   $('#cart_details').fadeIn();
   
  }
 });
}












 
 
It simply sends the form to the cart.cfm and adds the products to the cart. It then displays the cart in a little area of the page.
 
My problem is that this code does not work at all in IE8 with protected mode turned on. It fails on the "success" portion where it is just not processed. It acts like it is completely ignored.
 
I have even put just an alert in the success portion and it never reaches it.
 
Is there something I have to do to make this work in protected mode or is there a way to detect if the browser is in protected mode? I don't have a problem with this in any other browser but IE8.
 
Thanks,
Phil
