I pretty often get this message saying that "The TCP/IP connection was unexpectedly terminated by the server." It's when I change from one newsgroup to another this often happens.
I found on tip mentioning to uncheck Tools>Options>General>Use newsgroup Communities support features but that didn't help for me.
Even with the latest released Windows Live Mail 2008 I get this.
Any ideas on how to get rid of this message or the underlying cause?
