Can't access all aperture pics through photo browser
I recently migrated from iPhoto to Aperture. I still have a bug. As said in title, I can't access all aperture pics through photo browser. For example if i want to upload a picture in Facebook, i can choose in safari dialog Aperture libray as a source but i don't get access to all pics. Some are randomly missing. I don't know what to do. Any idea ?
