  • recording a current position in a stacking order of each of the plurality of window objects in an object identifier table in association with a corresponding object identifier;

    changing the position in the stacking order of a first object in response to a first user action for selecting the first object;

    recording the position in the stacking order of the first object before the position is changed in the object identifier table as a previous position in the stacking order;

    changing the position in the stacking order of the first object with the previous position in the stacking order of the first object in response to a second user action for restoring the changed position in the stacking order of the first object to the previous position in the stacking order; and

    lowering a position in the stacking order of a second object in accordance with a predetermined rule in response to the second user action performed for the second object, on condition that a previous position in the stacking order is not associated with the second object.
