I am creating a map that is a hodgepodge of databases, stand alone shapefiles, and a couple image services. Everything seems to go as expected until I add a certain shapefile to the mix. Then all of the other shapefiles disappear. Once that layer is removed from the map, everything else is fine. Only shapefiles are affected. The shapefile in question (as well as all others) display properly in 9.3. And, I'm adding other data that displays from the same folder, so it's not that I'm unable to access it. I've searched for similar incidents, but have came up empty.
