I have a laptop that has trouble bringing up the World Topography basemap in ArcGIS Explorer. It starts up with the World Imagery basemap, and I can navigate around that just fine, but I click to change it to World Topo and it just sits there without the view ever changing (I waited at least 5 minutes). It doesn't completely lock up the program, but I can't do anything in the map pane, even after going back to the My Default map. I tried uninstalling and reinstalling build 1500, but it didn't fix anything.
The laptop is a Dell D820 with 2GB RAM and running Windows XP; I don't have this problem on my desktop PC with 4GB RAM and running Windows 7 or a D830 laptop with 4GB RAM and running Windows XP.
Ideas?
