I just picked up a used Canon 20d from Adorama. It came with all the software that I installed on my computer running Vista home edition. When I hook up the camera to the computer and open the eos viewer utility, the camera is recognized, and the thumbnails display in the window as .jpg. However, I can do absolutely nothing with the thumbnails, can't save, edit, move, anything. Almost nothing on the dropdown menus is highlighted, with the exception of 'delete images" option. I can't even click on them to bring them up to full size, I just get an error message when I try that. If I disconnect or turn off the camera, the images disappear from the screen. I also tried using the zoombrowser already installed on the computer from my Canon p&s, but it won't recognize the 20d. Any thoughts?
