Well, you're probably right about that being the reason. However, I don't think mIRC's behavior or documentation should be dictated by broken servers, as that's rather unfair for people on networks that do behave sanely. In fact, the latter group appears to include three of the top-10 IRC networks right now (Rizon, ChLame, LinkBr) (I didn't look very carefully so correct me if I'm wrong). I see the issue though; perhaps mIRC could test the server software name against "unreal" or something like that, to retain its current behavior there? I believe it's doing similar things for other cases already?
