I have a client who is embedding my tours using iframes in a lightbox that pops up when the user clicks a thumbnail.
Unfortunately, it appears that fullscreen does not work on HTML5 (Flash is fine) because the HTML version goes full screen by filling its viewport; with frames, this means the iframe defines the viewport, not the parent page.
I am wondering if it will be possible to support iframes in HTML5 by using the DOM to move the krpano div to the parent page for full-screen mode when an iframe is detected.
Or should I just suggest that my client avoid frames?
