Hey guys quick question. I have this code that brings in data from a php script and it works fine in fire fox and mostly opera except one problem. In opera if I keep refreshing the page, once in a while the information will not appear at all. Is this possible to fix? Thanks in advance for any assistance.

$.getJSON(files+"comments.php?action=view&load=initial&topic_id="+topic_id+"&t=" + (new Date()), function(json) {
            if(json.length) {
              for(i=0; i < json.length; i++) {
                $('#comment-list').prepend(prepare(json[i]));
                $('#list-' + count).fadeIn(1500);
              }

            }

          });
