`WS_CHILD` is a different kind of child window that what we define as child window. See http://forums.codeguru.com/showthread.php?491604. Setting this style flag seems to mess things up a bit in our configuration. The name bar is actually being overlapped by the Windows task bar then. Not totally sure why this happens, but I think it's because windows with the `WS_CHILD` style are positioned relative to the parent, not the desktop (screen without taskbar). So it uses the full space available when maximized, which isn't clipped by the taskbar anymore.
