A changed nick should not affect a PM unless you're not in any common channels when the nick is changed. And if you're not in any common channels, there is no reason the server would tell you that the nick was changed, so mIRC can't display that for you.

As far as disconnecting... having it check all open PMs when someone disconnects from a channel you're in would not be a bad thing. But if they aren't in any common channels and they disconnect, then just like above, mIRC can't tell you they disconnected until you try to send a message.
