I have Picasa on my Mac because its web albums are a nice way of sharing photos with family and friends. I recently got Aperture 3 and now organise and keep all my photos in the Aperture library. Now, when I open Picasa it is crazily creating "folders" in the left-hand panel. But it is created folders that don't exist, with names that are just long random strings of letters and numbers. it seems to treat every single Stack in Aperture as a separate folder. Anybody else seen this and know how to stop it happening? Cheers!
