It used to happen with a lot of screen readers, and animated gifs were onne of the culprits. It wouod be interesting to find out what screenreaders still cannot cope with animations. Also, people with photosensitive epilepsy can suffer from animations at certain flash rates.

If so, is this a > concern? The real problem with animation is that it causes the human brain to lose its focus.

This is why banner adversts particularly like animation. -- Charles McCathieNevile http://www.w3.org/People/Charles phone: +61 409 134 136 W3C Web Accessibility Initiative http://www.w3.org/WAI fax: +1 617 258 5999 Location: I-cubed, 110 Victoria Street, Carlton VIC 3053, Australia (or W3C INRIA, Route des Lucioles, BP 93, 06902 Sophia Antipolis Cedex, France)
