+//      size so the standard: Y = ParentHeight - (Y + ControlHeight);
+//
+//  2)  The controls are direct children of a frame
+//      In this instance the controls are actually children of the Frame's
+//      client.  During creation the frame's client resizes several times
+//      during creation of the status bar and toolbars.  The CFrame class
+//      will take care of this using its AlterChildPos proc.
+//
+//  3)  The controls are children of a panel, which in turn is a child of
+//      a frame.
+//      The panel may be one of many, in which case the same treatment
+//      as 1 applies. It may be the only child, though.
+//      This is the nastiest case.  A panel is created as the only child of
+//      the frame and as such, when a frame has only one child, the child is
+//      expanded to fit the entire client area of the frame.  Because the
+//      controls are created BEFORE this occurs their positions are totally
+//      whacked and any call to WinQueryWindowPos will return invalid
+//      coordinates.  So for this situation we have to compare the size of
+//      the panel at control creation time with that of the frame client.  If
+//      they are the same we can use the standard Y position equation.  If
+//      not, then we must use the Frame Client's dimensions to position them
+//      as that will be the eventual size of the panel after the frame resizes
