4487 // client. During creation the frame's client resizes several times
4488 // during creation of the status bar and toolbars. The CFrame class
4489 // will take care of this using its AlterChildPos proc.

4496 // the frame and as such, when a frame has only one child, the child is
4497 // expanded to fit the entire client area of the frame. Because the
4498 // controls are created BEFORE this occurs their positions are totally
4499 // whacked and any call to WinQueryWindowPos will return invalid
4500 // coordinates. So for this situation we have to compare the size of
4501 // the panel at control creation time with that of the frame client. If
4502 // they are the same we can use the standard Y position equation. If
