This only happens in IE. I am using the PanelBar's onclik event to load content using the RadAjaxManager.
When clicking the link, there is a slight (perhaps 4px) movement up and down.
You can see this also here:
Click on 'others' and then any of the 3 links, you will notice that the page goes down a little - scroll it back up again and the same will happen when you click another link. When Ajaxed then the goes down and then back up again automatically and looks real bad.
I have tried other skins to no avail.
I notice that the PanelBar now adds a "#" to the URL - is IE looking for an anchor?
