I guess how bad the glitch is, is dependant on if you are using a proxy because you have to, or to evade a server ban.
But coming on here, threatening to use some other irc client if the problem isnt fixed, really doesnt concern Khaled, in fact, he suggests you use them if you do not like mIRC. I can only recall 2 times i have heard of this error: 1 from you, and 1 from RuFy, in this thread. Problems get fixed in the order that Khaled chooses to fix them, which in most cases is the order finds them, or we find them and tell him, or in the rare case of an exploit, which is fixed within about 3 days to 1 week.
Im not trying to chew you out, i am trying to show you how to get the problem fixed, ask nicely, things work out better that way.
