There shouldn't be a wall loaded with DX. That could be from the last theme you used. If you're trying to get rid of it completely, go to the DX Settings window (seen in your screenshot). Then go to the Desktop tab, click on the 'wallpaper' button. Uncheck 'background image' if it's checked, click the 'none' button. Close then apply.

Yeah Ed, I don't get a wall loading with DX

Ed, in the Summary part, of the clock hands, you can adjust the height and width, but right click on the hands themselves, and select the config option, you can change the color, and thickness there also, and anti-aliasing

hehe not a bad wall!! lol

Okidoki Ed, and I know you'll do great

hehe Yep, he knows that hon,  he's just trying to customize the plugin hands a little more, but there's only so much you can do.
