>>TITLE XForceScreenSaver CH07
>>ASSERTION B XForceScreenSaver-1

>>ASSERTION B XForceScreenSaver-2
When the specified mode is ScreenSaverReset and the screen
saver is currently enabled and activated, then a call to
XForceScreenSaver deactivates the screen saver and the
activation timer is reset to its initial state as though
device input had been received.
>>STRATEGY
Touch test for ScreenSaverReset only.
