   I have a layered window sitting on top of an MDI view.  It has no border and I've use SetLayeredWindowAttributes with LWA_COLORKEY so that it has a transparent background and is masquerading as part of the view.  My problem is that when an unpinned pane slides out, it appears under the layered window, so that the layered windows' controls are floating on top of the pane.  I see similar behavior in the docking pane samples: unpinned panes seem to slide out under floating panes.  How can I control who is on top?  I've been experimenting with SetWindowPos, but I can't seem to hit on the right combination.
