1-1/2 yrs ago I bought the Coolpix p7100. I love it, great point & shoot. I declined the extended warranty from the store. Last night my wife took it to a school prom. She was indoors so the flash popped up. 1st shot goes off , she thought she smelled smoke. 2nd shot -she sees & smells smoke coming out of the camera where the flash pops up. The front of the flash has a mark on the inside of the glass. When she brought it home I tried it out with the flash. It seems OK, it fires- no smoke. the image looks fine. WTH??? Is this common? Has anyone here heard of this happening before? I spent $500. on this camera, it seems ok, so I will continue to use it. Any thoughts or ideas????
