Haven't seen this problem listed. I have a slider in a sidebar widget that has a fast refresh speed: http://www.wser.org/ It works great except the page is longer then what can be seen on the screen. Whenever the slide refreshes it causes the page to scroll until part of the slider is visible in the view-port. This will cause usability issues if someone was trying to read text at the bottom of the page.
Is there a way to keep this functionality but stop the page scrolling?
