If you're using a version of Windows earlier than Windows 7 you just need to go to preferences and check the Clear wallpaper on exit option. This only half work in Windows 7 because of Microsoft's own wallpaper manger running in the background. All the settings are set correctly when AWC exits but Windows doesn't clear the screen until you log off and back on again.

When you say that applying a picture to the background goes fuzzy what exactly happens? AWC should be able to resize any image pretty smoothly to fit your screen unless the originals are very small indeed.
