My P200 has a mark on one of the inner lenses. An example of the smudge marks is [here](http://3.bp.blogspot.com/-mjDZBITednw/TdlGKv2u0uI/AAAAAAAAAeE/BefKHSp4JTc/s1600/58_Tucapau.JPG) (above the green house). The smudge appears in every photo in the same spot. I did some [stuff on my own](http://users.zoominternet.net/~ed.murphy/dustbunny.pdf), but the smudge remains. Is there anything else I can do?
