Just wanted to post a heads-up. There is a conflict between Microsoft's update KB951748 and ZoneAlarm. Something about that update will cause ZoneAlarm to block your browsers from internet access and ultimately shut your connection down. ZoneAlarm is recommending that you uninstall this update as a fix for right now. Turning your ZoneAlarm setting down to "medium" will also fix this problem, but obviously will reduce the level of security provided by the program.
This kept me occupied at work for at least an hour today. The ability to drag the map (or, if you prefer, use your arrow keys) is the greatest thing since the internet, and the maps are absolutely gorgeous.
