Hi,
I've been trying to process raw files from my 5D MK2 using the latest version of dpp 3.5.1. I download images using a card reader, when I start dpp and navigate to the folder on my desktop and then select it I get the thumbnail view of the files in the folder but the images are not visible! I can see the box where the image should be and the "raw" icon and also the shot number are all there but the image is invisible. I can see the images when I use the canon file browser utility so I know there is an image with that shot number. When I select one of the "invisible" images as if I were going to process it a larger window opens with nothing visible and I get the spinning ball of death and have to force quit the app. I'm using a Mac G4, 2 gigs of ram on Tiger 4.11. I also tried to process raw files from my 40D and have the same problem. It seems this version of DPP is not happy on my Mac. I normally use Lightroom but it does not yet support the 5D MK2. Any suggestions would be appreciated.
