iPhoto 9.4.2 update completes but isn't recognized by app store
I have a macbook pro running OS X 10.8.2. After successfully installing the latest iPhoto update, the app store still thinks the update isn't installed. Within app store update page, there's one update t install, iPhoto 9.4.2 is listed but then to the right shows "installed." Thanks for any insight to this. Maybe it's a non-issue. I've forced quit iPhoto and rebooted.
MacBook Pro, OS X Mountain Lion (10.8.2)
