would this be a good place to ask for troubleshooting help? for some reason my osx wallpaper turns on randomly, like while im using my macbook. i even have it set on "Never" but it turns on right in the middle of browsing the net. i figure it has to do with something i have installed, but i havent installed anything new recently. anybody heard of this? i have insomnia and caffeine, which i use all the time. one of those to the culprit?
