Whenever I use Slideshow in Preview with images, the images are very blurry, like if the screen was shaking and I cannot read text at all. In normal window mode without fullscreen slideshow, the images are crystal clear, though. I want an image viewer for OS X 10.6.3 that I can view in fullscreen mode like Preview, except does not make the images blurry upon fullscreen. Also need the capability of opening images that are within folders within folders (within folders, etc.). Do you guys have any suggestions?
