I'm having problems with mirc and irssi-proxy. irssi-proxy is a feature of the irc client irssi, which makes it work like a bnc/proxy. The problem is that if I connect to the proxy, I only get half of the channels I'm on autojoined. If I try connecting to the proxy with another irc-client, like BitchX, it works fine, all channels are autojoined. I'm using mirc version 6.1, but I get the same problem on 6.0 and 6.03.

Any suggestions?
