My *ist DS (c.3 years old) has an irritating problem that occasionally happens on a change of batteries. When the batteries run out and I put in a fresh set (either NiMH rechargeables or, as a back up, Duracell AAs), sometimes the camera fails to pick up the fact the batteries are fresh, and continues to report dead batteries.

This sounds like it might be similar to the problem reported here a couple of years ago, for which no solution/explanation appears to have been suggested. Does anyone have any ideas as to what this problem might be?
