Hey Kirby
I appreciate the fish. What I meant was, I wouild Force quit through the 'Force Quit' window, the process itslef would disappear from that window but he app would continue to hang - it wouldn't shut down.
I did repair / rebuild the library after this fiorst happened, that's why I'm concerned.
How does one 'look for images with corrupted originals ?"
Tony, the onlt thing I didn't do on Apples list was the.plsts, but I'll keep that in mind.
FYI, I also emptied my Aperture trash, which aparently most 'trash empty' applications don't pick up ( didn't know that )
I got some work done last night after a complete restart, but it feels like Aperture gets slower the longer its open, or if you work too quickly.
I'm on 10.7.5 with all the latest upgrades with 32 GB RAM, so speed and space is not an issue.
