Abstract
A computer program for rendering a magnified graphic user interface (GUI) establishes a first magnification level for the graphic user interface and a second magnification level for a pointer. It displays the magnified GUI at the first magnification level and monitors application program interface messaging for a call for a system pointer identifier. It intercepts this call and scales the pointing indicia not to the magnification level of the GUI, but to the second magnification level for the pointer. The pointer is then displayed to an end user of the computer system at a magnification level that is different from the magnification level of the GUI. Thus, the invention provides for independent magnification of the graphic user interface from the mouse cursor or caret.
