ABSTRACT:
A cursor manipulation system and method provides for interrogation of the most recently displayed cursor location upon the occurrence of a user-generated event, such as actuation of a mouse button, to avoid errors of input to an application due to delays in rendering of cursor images. The coordinates of a displayed cursor location are stored as an acknowledgment of completion of display of a cursor image at a new location. Specification of cursor display location is determined by a graphic input device corresponding to each cursor image and applications running on a data processing system including the cursor manipulation system are isolated from control of cursor movement.
