Is it just a webcam, or a digital camera too? Mine is both, and it has a camera setting, an off setting, and a webcam setting. I've discovered that if I leave it on webcam mode and plugged in, it randomly takes pics. If I make sure it's turned off, it doesn't do it. Kinda freaked me out the first time I came back to the computer and the webcam software was open and there were like 10 new pictures Fortunately, when I'm not actually using it as a webcam, I put it on a shelf in my desk, so it was just pictures of a bunch of books...lol. I finally realized what the problem was, and it hasn't happened since.
