Like the title says, randomly throughout the day, my desktop wallpaper will stop changing itself like it should. When it does this, it actually creates a NEW theme of my theme with just the one wallpaper and slideshow turned off. I can't figure out what it is that is causing this, but it's really starting to irritate me. Every time it does this, even after reboots, I have to go into personalize and change it back to my original theme, since it is for some reason set on the clone of the theme without multiple wallpapers... then I have to delete said fake theme. Does anyone know why Windows 7 is doing this to my theme without my command?
