    return;
}

jQuery.fixBlink = function(speed) {
    var visible = 'visible';
    setInterval(function() {
        // search the DOM each time in case new elements are added
        $('blink').css('visibility', visible);
        visible = (visible === 'visible' ? 'hidden' : 'visible');
    }, speed || 500);
