Been having a problem with this camera recently.Video comes out fine. But when I try to take a picture, it'll focus, and after I click the button, sometimes it'll take a picture, sometimes it won't. I can change the flash type (of, on, redeye reduction), I can switch to manual, auto, or pre-set mode, and it still has the same problem. It'll focus, I'll go to take a pic, and *click* and nothing. Again, and again, out of like 5 or 6 times I might get 1 picture.What does it sound like? Does it sound fixable? Cheap, or do I need a new P+C camera? (I got a D80, but I like a small quick P+C for fast shots).
