I'm using a theme modified from a Deviant Art, "Classic AE 2.5 Final" by ~Saarineames on Deviant Art (direct pointer
http://saarineames.deviantart.com/art/Classic-AE-2-5-Final-248970467), and the Microsoft Internet Explorer address bar overlaps the Window titlebar for IE. The screenshots below are made with the unmodified Classic AE 2.5 Final theme, not my modified version, to remove my work from the question. This is the IE window
and this is a normal window (Windows Explorer in fact)
What can I look at to get IE back in its box?
