Hey, 
I asked about this on the Hardware list, but got not solutions.
To keep the kids from messing with a particular computer, I added a pw to an
existing user. When the machine boots up, the background image is there.
Once the screen saver (standard XP logo one) has kicked in, I require that
the pw be entered to unlock it again. Once this happens, the background
image is no longer there.
I even copied the image to the same directory where Windows keeps it's
background images.
Any one know what's going on here? 
Thanks, 
Bobby
