jQuery Tabs not working in IE7 when Ajax option async: false

jQuery Tabs not working in IE7 when Ajax option async: false

Works on all the others: FF, Safari, Chrome and IE8 but not in IE7 (didn't test IE6 and don't care either), When trying to change tab it get's stuck.

Found something on StackOverflow about synchronous ajax call in IE7:

First answer:

I stuck my "success" functionality in the success block for FF and in the error block wrapped in an "if (xhr.status == 200)" conditional.

Is there any way I can do that without having to patch jquery?

Thanks
