1. The long press routine was using the coordintates of the
accessibility focused item in the input focused window.
As a result double tap and hold did not work in a window
that does not take input focus such as the system bar.
Now the routine is using the last touch explored location
if it cannot find accessibility focus in the last touched
window.
