/* The propertysheet has a method to delete itself and repopulate
 * if the "control" property changes. Pre 4.5, the control property
 * might not be the first one, so, the properties are stored and
 * re-applied. If the "control" is the first one, it should be
 * sufficient to reapply the changed flags, however, care must be taken when
 * resetting the control.
 * Resetting a control: The current behaviour is that the modified Active X properties are added again
 * as Fake-Properties, which is a nice side-effect as not cause a loss. */
