Do you get a Solid black or some other colored background when you restart If so DS crashed..
If you get the Dream wallpaper but it's not moving try right clicking on the Desktop and if available click resume deskscapes
if not there, more then likly it crashed and you would have to restart it.
Note right click on desktop and you can get to the interface of DS by clicking on Configure Deskscapces.
hope this helps
