Thickbox does not show scrollbar in ipad and solution

When I use thickbox to popup an iframe in my page, it shows in ipad WITHOUG scrollbar. Solution: 1) Edit thickbox.js Find tb_init(), add // identify the touch device if ("ontouchstart" in document.documentElement){ $('html').addClass('touch'); } 2) Edit thickbox.css Add: .touch #TB_window { height: 90%; -webkit-overflow-scrolling: touch !important; overflow: scroll !important; }
