Hiya,
dburr, it doesn't sprall as much as yours and mines a little bit more see through, but yeah it does. Could it be a young black sponge that is forming? I've only had it for about 5 days now.
I did try to take more pictures, but the flash made it worse. I've got a sony FD Mavica 2.0 mega pixels. We bought if off the shelf so didn't get a book with it.
