Previously I used Iphoto to import pics from my Canon camera. After installing Snow Leopard, I can no longer import photos. My camera only shows up if I have Iphoto open. Iphoto shows all my pics on my camera, but doesn't even let me click on "import photos." If I select a photo or photos and drag them into a folder in Iphoto, it will say "importing" but never actually does it. Now when I try to quit or do anything a box pops up and says "photos are being imported to the photo library, please wait for import to complete." Help!
