My Canon Z115 has been a great camera until now. Most of the time the display shows a flashing letter E. Sometimes it will go away by moving the selector dial to other positions. Other times removing the batteries and reinstalling them resolves it. Other times, like now, I can't get rid of it thus the camera is inoperative. There's been a few discussions on this but nobody had a solution. Did anyone have this problem with the Z115 and fix it? Thanks.
