4493 // client. During creation the frame's client resizes several times
4494 // during creation of the status bar and toolbars. The CFrame class
4495 // will take care of this using its AlterChildPos proc.

4505 // whacked and any call to WinQueryWindowPos will return invalid

4507 // the panel at control creation time with that of the frame client. If
4508 // they are the same we can use the standard Y position equation. If
