This problem is not caused by The Panorama Factory.
It is caused by using an older version of the QuickTime viewer that does not support
the QTVR format. It displays the QTVR image as though it is a conventional QuickTime
movie. In addition to being flipped 90 degrees, the image plays as a movie.
That is, it plays through the panorama from one end to the other and you are unable to
control the position using the mouse.
