Picasa for Mac's newest version 3.0.6 still uses 90% of my CPU with a test set of only 100 (!) JPG images when Picasa has focus - even after hours...

I really would like to know what Picasa does here in the background with your data - especially since it's offered by Google.

It's a pity... - I would really like to use Picasa if its developers finally would offer a version of Picasa like in earlier Windows days when version 2 didn't eat up all your CPU and offered the same core functionality: just an overview of all pictures stored on your hard disk.

But with this new version it's still a CPU nightmare.
