i'd entered login and password in proxy settings..
logged on network..
at next start mirc can't connect to server..
log message:
[16:07] * Connecting to irc.ru (6669)
[16:07] * Firewall: Closed connection

(i dont have any firewalls installed, default winxp firewall disabled. connectig via squid installed on our FreeBSD gate..)

only when i change login and password to another valid - it starts to see irc server..
if i restart client, mirc doesn't want to connect again, until i change login and pass.. again.. and again..

something in mirc with proxy authentication..

Thanks, this issue looks like it is related to this post, it has been fixed for the next version.

ohh sorry, before post msg tried to find something like this on forum, unsuccessfully..
