ABSTRACT:
A computer system includes a display screen, and is capable of displaying in a portion of the display screen (i.e., a "window") a portion of display data generated for display on the entire display screen. The computer system includes a first memory structure for storing data generated for display on the entire display screen, the fist memory structure receiving data in a manner independent of the size and location of the window on the display screen. A second memory structure contains data corresponding to the data stored in at least a selected portion of the first memory structure at a first point in time, where the portion corresponds to the display data displayed in the window. The computer system further includes a detection structure that, at a second point in time, compares data in the second memory structure with data in the first memory structure to determine whether a change has occurred in the data stored in the selected portion of the first memory structure between the first point in time and the second point in time. An updating structure updates data displayed in the window with data corresponding to data stored in the selected portion of the first memory structure at the second point in time if the detection structure determines that a change has occurred in the data stored in the selected portion of the first memory structure between the first point in time and the second point in time.
