Looking for some help... just got a new MB unibody. Tried opening photo files via a card reader to work on Photoshop (I am using Sandisk Extreme iii SDHC 8 GB). Problem is, Finder can "see" the file, including the little preview icon. But when I try to open in Preview or Photoshop, I can only see part of the file (a vertical line). Seems like I don't have "access" to these files (based on the error message, but I am logged in as admin). I had no problem accessing the photo files via my old white MB. Anyone run into this problem? Tks for any input.
