Originally posted by dborked I don't but then I usually hold it with one hand down by my leg so I've never encountered any issues with any settings being changed whilst not using it. I would take jatrax's advice and just shorten the Off timer.
I leave it on all the time, and have the timer set to a very short auto off time interval.
Usually wear the camera over my shoulder, with my left hand on it, in case the strap lets go, which has never happened...
I leave the mode unlocked, but occasionally it is half locked, which is annoying, but not major.
I guess I don't like the camera to bounce off my chest...
