 Continuous MDI background transparency

Does anyone know how to make an MDI (CMDIFrameWnd) background remain
transparent (but not the Child Windows) even while dragging the MDI window
around the desktop?

 I tried using the WS_EX_TRANSPARENT extended style setting, but this works
only one time (a snapshot of what was behind the MDI window before it
appeared). I need this transparency to occur as long as the MDI window is
displayed because I'll be monitoring other applications running behind the
MDI window.

Your help would be appreciated.

Offhand,  I would  try to override OnCtrlColor with:

        hbr = (HBRUSH)GetStockObject(NULL_BRUSH);
        return hbr;
