    • WM_IsCompletelyVisible doesn't seem to work

      Hi there,

      WM_IsCompletelyVisible for a window always returns 1/true even when the window obviously not fully visible, half of the window is obscured by other sibling window.
      Tried to use WM_HBKWIN as a common parent to all windows. Also tried creating "root" window that covers whole screen and is parent for all others.
      No luck in either case.
      Would appreciate any suggestions on what might be happening.

      Many thanks.
