I can't find a word of this problem anywhere on the interwebs. I have iPhoto 5.0.4. I have been able to export photos with no problems. Two things happened. I got the vanity URL from Facebook, and I got the upgrade for Facebook Uploader For iPhoto Photos. Since then, I haven't been able to upload a photo. When I click 'Export', nothing happens. Absolutely nothing. Updated Stuffit Expander, went through every relevant article I could find online- NOTHING seems to help. Anyone out there have any ideas? I could sure use them before this sledgehammer nails either the Mac or the center of my forehead...
