Any wallpaper fans here? I personally like my pool of wallpapers on aperture. I set them to be background on desktop. I don't remember since when, I started to see the updating (change every hour) broke every once a while. Then I had to go to sys pref to reset the background. I thought this glitch would go away by itself, but it never did. I have no idea what could possibly cause this problem. I tried to migrate my wallpapers to iPhoto and change the updating rate from once a hr to once a day... Nothing helped at all. Any idea? Thx.
