Recalibrating Touch screen
It should be rare to recalibrate the touch
screen, but in some cases it could be
reasonable to recalibrate it, for example, if the
touch screen has no good response to
tapping it. However, it is normal that the
response time to tapping some display object
on the screen varies because it correlates
directly with the load of the processor unit.
Before you begin, open the ‘Stylus’
control panel applet (see section ‘Control
Panel’ on page 30).
