In many of the shots I've taken on my Canon P, there's a horizontal bar that shows up along the right or left side of the picture--it varies, but it never occurs on both sides in the same picture, and it occurs with different lenses. It sounds like it would just be a light leak, except that you can often see details of the adjacent shot imprinted in the horizontal bar. An example: I've scoured the internet for similar cases, but to no avail: what is going on here? Is this simply a light leak? Something more insidious? Or the kind of issue where one can simply bend a part here or put a piece of tape there to make it go away? Thanks!
