I just noticed a sorting problem with iPhoto '11 (v. 9.3.2) on Mountain Lion. Prior to upgrading both to Mountain Lion and the current version of iPhoto I had pictures in several events sorted by title instead of the default date. I just added a few pics to two of those events and noticed that the sort order for those events switched back to date. Now, even if I change the sort order back to title, when I close and then re-open iPhoto the sort order has switched back to date for those two events. My other events are still sorted by title. Anyone else notice this or have any suggestions. I assume it's a bug that will need an update to fix.
