On the server tophost.azzurra.org, typing /list triggers a raw 447 saying you must be registered to use /list (that is, if you are not identified)
mIRC is not prepared for this, mIRC will stay in a state where it is waiting for some replies.
That will cause several issues, listing them is not useful, it goes from getting the channel list to popup empty when you create a new server window to not being able to close the channel list at all until you reconnect. Tested on a clean 7.35.
The behavior of the server is most likely not correct but I thought I'd report this because it can affect others connections, so mIRC overall.
