Abstract: An application or terminal emulation program, which is being executed on an information processing system, is represented by the display of a first icon on a display device. If during the execution of the application or terminal emulation program, a virtual display buffer associated with the application program, is updated, a second icon is displayed on the display device to indicate to a user of the system that a change in the status of the program has occurred.
