When I read a message signed by a gpg key that is not already on my keyring I have runaway cpu usage. To end it I have to 'killall gpg' - at which the display returns, but of course it has not connected with the keyserver, so the key is not downloaded and I get a 'signature not verified' error message.. What's more, although the display has returned, I have to 'killall gpg' a second time, to return cpu usage to normal. I'm at a loss where to start troubleshooting this. Could it be a firewall problem? Anne
