if u look at the title, its mIRC tut. not vcmp server tut.
anyway, if i understand corectly, u mean a bug, that when u choose class, at times, the skin freezes to the same skin. well, thats using special skins with normal ones. i dont know where the line is precisely, but i think its somewhere round 120.
btw, i dont have any knowledge of setting classes color. i dont think it possible, but of course, it wasnt me who programmed it.
