4539 // 2) The controls are direct children of a frame
4540 // In this instance the controls are actually children of the Frame's
4541 // client. During creation the frame's client resizes several times
4542 // during creation of the status bar and toolbars. The CFrame class
4543 // will take care of this using its AlterChildPos proc.
4544 //

4552 // controls are created BEFORE this occurs their positions are totally
4553 // whacked and any call to WinQueryWindowPos will return invalid
4554 // coordinates. So for this situation we have to compare the size of
4555 // the panel at control creation time with that of the frame client. If
4556 // they are the same we can use the standard Y position equation. If
