ie6 7 ajax无效,IE6/7 Freezing during jQuery AJAX request

I'm using the following code to call in some html, and display it. Most browsers seem to handle it fine, but IE6 and 7 freeze up. Unfortunately, the request can sometimes take more than a few seconds, so the delay is noticeable.

I'm also calling Fancybox on success, so that the returned html can have a link that launches a modal window.

Code:

$.ajax({

url: 'url',

success: function(data) {

$('#videolink').hide();

$('#videolink').html(data).slideDown();

$("a#video").fancybox({

'hideOnContentClick': false,

'transitionIn' : 'elastic',

'transitionOut' : 'fade',

'titleShow' : false,

'scrolling' : 'no',

'onStart': function() { _gaq.push(['_trackEvent', 'Event Title', 'Value']); },

'callbackOnClose': function() { $("#fancy_content").empty();}

});

}

});

Is this the best way to handle the request?
