I am having a strange problem w/ holes appearing at the top and bottom of a spherical gigapixel pano.
http://www.xrez.com/krpano/html/diving.html . I am using my existing 256 pixel wide tiles, not the 1k you used Klaus in your example made with this same image. I am using flash 10 but I tried playing around with the <details> numbers anyway and this did not change the result. I am not sure what to try next.

Strangely when I am using the same code locally with fewer zoom levels the problem only occurs when zoomed in. I suspect the number of zoom levels may have some influence on this.

Thanks Klaus! I feel pretty foolish now. Sorry for the wild goose chase.
