Paraphrasing Alex…
“If you click on a radio button, IE seems to wait with firing the change event until you leave the button, which is consistent with the behavior on other input fields (like text)”

$(function () {
    if ($.browser.msie) {
        $('input:radio').click(function () {
            this.blur();
            this.focus();
        });
    }
});
