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.

4484 // the frame and as such, when a frame has only one child, the child is
4485 // expanded to fit the entire client area of the frame. Because the
4486 // controls are created BEFORE this occurs their positions are totally
4487 // whacked and any call to WinQueryWindowPos will return invalid
4488 // coordinates. So for this situation we have to compare the size of
4489 // the panel at control creation time with that of the frame client. If
4490 // they are the same we can use the standard Y position equation. If
