got a message on my new Powershot saying "Change The Batteries" so I put 2 new ones in and took about 2 pictures, then tried to take another picture and I get that same message AGAIN. This isn't right. What could be causing this message. Is this a common thing with Powershots? It doesn't even have much usage on it at all, as it is only a month old. Would appreciate any help in this matter. Thanks.
