/url bug, never happened to me.
Nick completion bug, never happened to me.
*** - * 'bug'. Boohoo, get over it. If you really enjoy looking through your logs so much and you happen to sit in a channel where people constantly try and take advantage of this then script your own display for them.
Maybe the first two really are bugs that occur, maybe your system is just messed up. Either way, there's no way to tell unless you actually give a real bug report instead of bitching and making idle threats about changing clients. And by the way mIRC isn't freeware, it's shareware.
