When clicking on a link to the Glouster Va GIS interactive mapping tool, Intrenet Explorer (9) shuts down. The mapping tool worked fine with earlier versions of IE. I am running Windows Vista Home Premium W/SP2. My motherboard is a Foxconn A7GM-S 2.0, my processor is AMD Athlon X2 260 3.20 GHz, and I have 4 GB memory installed. I also have internal 3 hard drives (1 TB, 320 GB, 80 GB) and 1 external 500GB, all with ample (60 to 90%) remaining unused disk space. When I restart the computer and switch to Win XP with IE7, I can easily access the mapping tool and it works fine. I have not tried to revert back to an earlier version of IE while using Win Vista.
