I'm running running OS X 10.5.8, iphoto 7.1.5 and have 2 users: my husband and myself. On my login, everything works as it should. On his, I keep getting the "can't open using this version" message. The pics open in Preview so I've moved a few into the shared folder, logged out, logged back in on my side and reopened them in iphoto, but this is pretty laborious and the he would like to edit under his own login. I can't figure out why the same version works for one login but not the other.
