the problem is, that the users do not understand what happend! User (a) using 6.xx invites a user (b) using 7.xx into a channel and he joins a complete different. That's weird.
Using svsjoin (with a 6.xx-client) I can join myself using a 7.xx-client into a "codepage-channel". So I receive every privmsg, but are unable to answer.
Tha same thing happend with users who use a join-list with nickserv.
You see, mirc 7.xx is completly inconsistent. No normal user understands what happend. Thats the problem
