Hi Mike,
Thanks for your response. I can't seem to load anything, the map display window just seems to freeze up. I thought it might be the video card, but I can use ArcGIS Explorer Online with no problem (Panning and Zooming).
I did load the ArcGIS Explorer Build 1500 with admin privileges (not the Current User version), and there are no other ESRI software products on this computer.
I've included a snapshot of what is displayed after loading a Basemap template. The blue area is the color of my desktop background.
Thanks,
Gary
