Do a /debug @debug and look at the MODE line returned by the server. Paste those lines for us. It sounds like a bug with how mIRC interprets MODE responses (if the server changes your nick on you, mIRC follows suit), and with CR sending a back a response with your lowercase nick.
So it's likely a bug with both CR and mIRC. mIRC's end of it seems reasonable though, it's only handling the data given to it. Other clients seem to ignore when the server lies about your nick, making mIRC a slightly more gullible client (I TRUSTED YOU!).
