I think there's a selection for which files to "View" in Adobe Bridge. Check the View menu.
Also, check to make sure the RAW file extension is CR2.
Also, close Adobe Bridge AND DPP, then open Adobe Bridge. Adobe Bridge does not work well file sharing with other programs.
Also, I agree that DPP does a good job of RAW file conversion *IF* you have the patience to tolerate the best example of how NOT to write software. Itís SLOW, UN-intuitive, and a very CRUDE interface. The only software that comes close to DPPís kludginess is Capture One. My guess is thereís some kind of relationship there.
