I recently went from JPEGs to shooting RAW images with a Nikon D80, so I have been converting the NEF files to DNG files right after they arrive in Lighroom 2.6.
My JPEGs always showed up as thumbnails (and still do) in 'My Pictures' on my HD, and NEFs would also be thumbnails (at least I think so) of the images--but NOT the dng files that have a blue/orange pattern that conceals what they are--and this is a problem, especially if I have to reconnect those occasional, pesky "?s".
I might be doing something wrong--or is this the way it is supposed to be--no thumbnails for dng files? Any suggestions? Thank you.

OS is Win 7 Ultimate (we get it where I teach for $19.95), on a (as far as I know) 32 bit platform (?). I should add that many (even most) images in the folders I am calling on are thumbnail views--but there are a lot of these 2-color jackets over the images. Computer is a laptop; 2.5 year old Toshiba.

So you are getting thumbnails on some DNG's but not others? (I'm on win7 x64 and I only have a few DNGs, but I get thumbnails on none of them). If you are not getting thumbnails on any of the DNGs you can try the CODEC, if on some but not others I don't know.

I said "Charlie (above) sent..." and I meant it. Mine was the original post, and Charlie was the first to respond to it and he sent the Adobe Codec then. LOOK ABOVE, at the post that says # 1 (yours is # 6) and click on the three letter word T.R.Y. that is in gold--that will bring you straight to the Adobe Lab in 3-4 seconds; then download the DNG Codec, and...WOW!
