This issue occurs in both picture-taking mode and movie-taking mode. In movie-taking mode the camera fails to write the movie to the memory card. The camera "locks" onto a random image and stops functioning. I cannot use the power switch to turn the camera on or off, nor can I take a photograph or command the camera to start/stop taking a movie. I must take out the batteries for 30-60 seconds, wherein the camera restarts itself. I have been unsuccessful in finding internet postings for this problem, so I am looking for ideas.
