Personally I think everything is as it should be.

The help file says "Note: You can't prevent the standard version reply from being sent."
and the Faq says "There is ONE exception to this ... you cant hide your mIRC version reply.... We like the advertisement, you know.... "

And I agree, "IF" you get/accept a CTCP VERSION from someone you cant stop it. But of course thats IF you accept the CTCP VERSION from them <grin> And i think we both know how to not accept it, and is that not our right to choose who we respond to and who we dont!
