Thanks for the replies.

I dislike these unpredictable behaviour. IE is still the most popular browser and web users will not know that the fault is in the player not the vr photo. And writing a warning next to the vr photo that they might have to re-install flash would be a big turn-off.

Strange. I created 3 panos in Flash, they worked coming out of Pano2QTVR. I uploaded them from my mac and they worked online with Firefox and Safari. I come to check them on Internet Explorer and nothing happens. Can someone with IE verify this and see if it loads or not: http://egypt.madeena360.com...
