When I set up a custom basemap using version 1200, I save it, close the app, and re-open it. I choose the basemap I made, it shows up as a really really tiny dot in a white screen. I then need to zoom in and zoom in to get to appear at the scale I want. What gives? I set the projection parameters in ArcGIS Explorer to the same as my basemap. Other default basemaps work fine.
