            A frame at (100,100) contains two (2) rows of three (3) text
            fields each, and under this, a checkbox labelled 'Use menubar'.

            The first row's text fields pertain to the x coordinates and
            the second row's text fields pertain to the y coordinates.

            The first column, 'request', is an input only field for frame
            location. (press enter to apply).

            The second column, 'reported', is an output only
            field reporting frame location.

            The third column, 'inset', is an output only field reporting
            the frame's inset values.

            You can click the 'Use menubar' checkbox to alternately add
            and remove a menu bar containing an (empty) 'Help' menu.

            After a menubar is added or removed, the frame should not
            have been resized nor repositioned on the screen and the
            y inset should accurately reflect the presence or absence
            of the menubar within the inset.

            The insets always include the window manager's title and border
            decorations, if any.

            Upon test completion, click Pass or Fail appropriately.
