Weirdest thing here: I upgraded from iPhoto 4 to 5, and am running 5.0.1. I organize desktop pics into iPhoto folders, which I then can go into Desktop and Screen Saver Prefs, chose an album and set it to cahnge every 15 minutes or so.
This has been working fine.. but I think ever since I screwed around with some scripts from Doug's Applescripts, namely the export iTunes album art to iPhoto one, I can no longer randomize my desktop pics from Desktop and Screen Saver prefs. The option is just greyed out on all my albums. I can still CHOSE an album for the desktop, but it can't cycle pics. What I've tried so far:
1) repair permissions, millions of times
2) rebuild the iPhoto library by holding cmd + opt when starting up iPhoto
3) threw out the iPhoto 4 legacy folder 'Albums' left over in the iPhoto Library folder
Any ideas? Thanks.
