4403 // client. During creation the frame's client resizes several times
4404 // during creation of the status bar and toolbars. The CFrame class
4405 // will take care of this using its AlterChildPos proc.

4415 // whacked and any call to WinQueryWindowPos will return invalid

4417 // the panel at control creation time with that of the frame client. If
4418 // they are the same we can use the standard Y position equation. If
