A computer system has a plurality of input pointing devices, such as a mouse,
a
track ball, a pointing stick, a tablet or a touch screen. Each of the plurality
of input devices connected to the computer system has different parameters associated
with a double-click operation, which different parameters are stored in separate
registers under control of the operating system. Separate device drivers are associated
with each input device, each device driver using the associated double-click parameters
as stored by the operating system.
