I had Capture NX2 on my MBP and because of Newspaper requirements, I had to download CS4. NX2 was my default application to open my NEF files, then all of a sudden CS4 is my default program. I did nothing. When I go to open with and then check on the "always open with" box, it opens in NX2 but then when I go to the next NEF, bang it opens it up again in CS4. Any suggestions on what I did? I am posting in the Apple slot too! Thanks for any help.
