Problems with MENU and deleting pics! Please help! I love the shots this camera takes, but either we touched something to screw things up, or there's something wrong with the camera. The Menu is no longer displayed when the MENU button is pressed, and when the camera's in Playback mode, we can't delete any pics! Pressing the delete button takes the camera back to the Auto shooting mode. Pressing the MENU button makes the lens zoom in as if I'm pushing the ZOOM lever. I read the entire manual and can't figure out what's wrong. Anyone else have this problem? The camera is new, by the way.
