It is possible to register more controls that have to be enabled/disabled
together with this helper object (optionally dependent on the stacked text
check box), using the function AddDependentWindow(). All registered windows
are handled on a call of Enable(), or Show(), or on changing the state of
the "Stacked text" check box.

direct modifications of the "Stacked text" check box. Otherwise the update
mechanism of registered controls will not work.
