When the taskbar is set to hide itself when the mouse is not over it, it will not be posible to bring it back by moving the mouse at the bottom of the screen if a skinned window is maximized.
This occurs when ExtendedBorders is True and NativeBordersMaximized is False.
If I activate NativeBordersMaximized, then it's the Minimize, Maximize, Close buttons that looks wrong (they are bigger that the title bar).
