Using AVS as animated desktop.

[Ton]

Through the FAQ's here I learned how to set AVS as a animated desktop. Very nice !
However I have one question about it and I hope you can answer this.
When I use this option I always have the AVS in the Winamp window as well, altough I can detach it and have a separate window with the AVS. But I always have the AVS twice, as desktop background AND as small window in or outside Winamp.
Is it also possible to have the AVS ONLY as desktop background, so without the separate window, and if so how do I do that ? Of course it is possible to set the AVS fullscreen, but this is not what I mean.
