You may have set the config's fixedcenter attribute to true..
I'm making a guess ... do you have the anchor's href attribute as :
<a href='#'>Your link</a>
> I have a dialog box which when made visible positions itself in the center of the browser no matter what the vertical scroll position. The dialog box has a link to a panel which supplies supplemental information about the dialog box.
> when the panel is shown through the link, the browser scrolls to the top of page where the panel is shown and the dialog box is redrawn. I tried setting the context of the panel to the dialog box but the browser still scrolls to the top of the page.
> Has anyone had experience with this and have an explanation how I can show the panel without the browser repositioning?
