4475 // client. During creation the frame's client resizes several times
4476 // during creation of the status bar and toolbars. The CFrame class
4477 // will take care of this using its AlterChildPos proc.

4487 // whacked and any call to WinQueryWindowPos will return invalid

4489 // the panel at control creation time with that of the frame client. If
