I've used the default News template's Login icon ("Login-top icon" module) and, when clicked on, the pop up briefly displays at the top of the page then the page jumps (scrolls) about 700 or 800 pixels down. I have customized the template as per the Gavick support instructions by adding a Leader Board position at the very top. It is about 90 pixels high. Maybe that is the cause.
How can this be fixed? The page jumps so far away from the login popup that it isn't visible.
