There is provided a method for manipulating display of multiple display objects on a display device in a data processing system connected to the display device, the multiple display objects being ordered and at least partially overlapping each other. The method includes the steps of: recording the current position in a stacking order of each of the multiple display 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; and 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. The method also includes the step of 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. The multiple display objects are preferably window objects.
