            var targetTabLink = $(this).parents('li').eq(0);
            $(targetTabLink).addClass('selected');
            $('.tab:visible').fadeOut('slow',
                function() {
                    $(targetTab).fadeIn('slow', function(){ blockAnimation=false; });
                }
            );
        }
        }
        return false;
    }
);
