Installed and quickly uninstalled this one, but the damage was done. My iPhoto Library was destroyed. To top it off, the install corrupted a Time Machine backup making all restore options impossible. I lost my recent Hong Kong/Australia images, but Apple gave me my money back for the software. Good trade, eh? Now they come out with a patch for iPhoto. It's like sand in the wound. I guess the beta testers were drunk. I wish I was, too.
