4486 // client. During creation the frame's client resizes several times
4487 // during creation of the status bar and toolbars. The CFrame class
4488 // will take care of this using its AlterChildPos proc.

4497 // controls are created BEFORE this occurs their positions are totally
4498 // whacked and any call to WinQueryWindowPos will return invalid
4499 // coordinates. So for this situation we have to compare the size of
4500 // the panel at control creation time with that of the frame client. If
4501 // they are the same we can use the standard Y position equation. If
