I have a RadWindow that is loading a URL (i.e. iFrame). The page that is loaded uses a sticky RadAjaxLoadingPanel (setup to cover the entire page). However, I am able to scroll the contents of the RadWindow while the loading panel is being shown over the page. And this gives me access to areas that should be protected by the loading panel. Is there any way to move or center the loading panel when a scroll happens in the RadWindow? Maybe somehow get a reference to the RadWindow's iFrame from the inner page so I can bind to the scroll event and change the top attribute of the loading panel accordingly? Or is there some way to put a loading panel in the RadWindow and trigger it from the inner page?
