It seems like it kind of works. When opening this the image
http://www.fortnet.org/FortNet/HTML/Presentation/animation/nph-anim.cgi
it only flickers. But after I klick reload the animation is shown
correctly. This do seem like a bug.

When the animation is included in a page -
http://www.fortnet.org/FortNet/HTML/Presentation/animation/ - it is
shown correctly right away, unless the image is in the cache in which
you have to press reload.
