My bad jugg, the black area being different sizes was a property of Clickonic not jdesk. You're right, jdesk covers the whole screen no matter what the work area is set to, and so do the other desktop modules.

DeViLbOi, I didn't want to imply that this is Litestep's fault, or a problem with Litestep, it's just a problem I've had involving Litestep, so I thought I'd ask here to see if anyone's come across the same thing.
