Fullscreen windows are rendered alone and above everything else when they are active, and as part of the regular window stack order when something else is active. Currently windows cannot be made fullscreen after-the-fact, but must have the fullscreen flag included in their CreateWindow message. It should not possible to interact with the menu, taskbar or window frame while the active window is fullscreened. :^)
