Abstract: Dynamically tracking the stability of application programs used in a computer system and for indicating the stability state of such programs to the user through a graphical user interface. Computer controlled user interactive display systems with graphical user interfaces store a plurality of application programs and present a GUI with a plurality of icons, each of which is representative of one of said application programs. A user is enabled to interactively select any of said displayed objects to thereby run the application program represented by the object. The rates of unrequested interruptions in the runs of each of said application programs, and there is an implementation associated with each of said objects for displaying a visual indicator of the rate of unrequested interruption in the run of the application program represented by the object. The interruptions tracked are primarily unrequested closings in the run of the application programs, i.e. crashes.
