Seems like a trivial thing to set up, but frustrated how long I keep trying this without success. I have two machines in my garage, both with Vista Ultra SP1, both are accessed using TightVNC client. The access utility has the same Options and Configuration settings. Just to make sure I always know which machine I am looking at I put a JPG file on each, one the number "5" and one the number "3." I selected 5.JPG as background for machine 5 with no problems. When I do the same for machine 3 it looks fine, but when I kill the VNC connection and log back in the 3.JPG is not used, instead the solid color background I started with.
