Yeah, this happens to me, less so nowadays. Always figured it was just the touch screen accidentally being activated? Trash can button (moves it back to centre) was my friend. These days I just turn off the camera off unless it is in my hands.Going crazy on this problem: when I let camera hang from neck, when I pick it up again and screen turns on, the focus point has moved. And if I move the camera, focus point blinks and erratically moves from center to new position.
