Abstract
A method and system for monitoring a computer program window define an area of a computer program window and compute a hash value for the defined area. The computed hash value is stored and the hash value is recomputed for the defined area after a predetermined time period. The recomputed hash value is compared with the stored. If the stored hash value and the recomputed hash value are different, the method and system overwrite the stored hash value with the recomputed hash value, and generate a notification. Recomputing, comparing, overwriting and generating are performed periodically to monitor the changes in the defined area.
