... have you left them on and returned to the vehicle with a "swipe" upon re-entry as has been reported previously?
I did the 4.2 update yesterday. Still does the single sweep of the wiper when the wiper left on on prior exit. Only does it when I initally sit down in driver's seat.
It would be nice if it delayed 3-5 seconds after sitting down to allow you a chance to get the door closed.
