Tor is unable to geolocate any exit nodes

Windows 7 SP1 x64

Hi,

I'm unable to successfully set strict exit node policies by country code. The reason is that the network map of Vidalia/Tor does not show any country flags and doesn't give me any hints about where a node is located. Exit node policies won't work because Tor seems to be unable to locate any node geographically. 

Any ideas? Thanks
