Anyone else having this problem? When I try to email photos directly from iPhoto, I get a lot of spinning beach ball and then finally a window that tells me there was a Mail error. Never had this problem with previous versions of iPhoto.
It works fine for me. You should probably delete the com.apple.plist in Home/Lib/Preferences. For more info (other people have had this problem) see http://discussions.info.apple.com/webx?14@271.1JZQaoEAQxK.1@.68adbd67 Good luck!
