Hi, I have a MacBook Pro running OS 10.6.6. Lately, when I try to set up Mosaic to be my screen saver in System Preferences, I see the progress bar saying it's setting up the database...and then it always crashes. I've tried everything; updating iLife, trashing my preferences file, selecting a folder with not so many photos to choose from...Nothing works! I love Mosaic and think it's one of the best screen savers ever. Why does it keep crashing and what can I do to fix it?? Thanks all!
