I recently migrated from a Powerbook running 10.5.8 to a new iMac under 10.6 and a few days later Lion. Just about everything went smoothly except for iPhoto. I don't remember if it worked under 10.6 becuase I had it for such a short time but with Lion each time I open iPhoto it tells me it needs to reload my photos or something similar. My photos do all appear but iPhoto freezes when I try to delete and clear out the trash. I am able to load new pictures into iPhoto, but I can't seem to delete them.
Just wondering if anyone else has had strange behavior from iPhoto under Lion?
