I have a cached map service of the County that I put in the background of most of my maps. When I use smaller maps (8.5x11) it shows up find and everything is great. But when I try to use it in bigger maps (36x48) it doesn't fully display. It loads on part of the map, but not all. Is there a setting somewhere on my service that I need to beef up? How do I make it so that the service will fully load?
