I have a problem with Iphoto icons. When importing photos to Iphoto everything seems to be ok until I leave the program and reenter it. When doing so all "Happenings" are like black boxes and all photos have the same icon. Actually the icon of a photo I used to have on the computor. When clicking on the icons the real photos show up. Is there someone ho has experienced the same thing and know how what to do about it?
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Include the option to rebuild the thumbnails. It can take 3 or 4 goes for this to work
