It happened on a bus.
BCN, taking the airport bus into the city one Friday evening for a long weekend. At a particular stop - the driver closed the double doors in the middle of the bus and they immediately re-opened. He closed them. They opened themselves. This went on for some minutes but he could not move, because the doors were open.
My lady said quietly, "Boot the bus". Eventually he did. Shut down the engine and all electrics off. Wait 20 seconds. Switch on electrics and start engine. Doors close and off we go.
It was almost certainly not windows (Windows? In a bus? Geddit? Oh, well please yourself) but was still a computer ...
