I just installed 6.3 and upgraded from 6.21. There is a new menu on the left side of the screen that lists the channels and queries that can be positioned left, right, top or bottom. First of all, what is this menu (or whatever it is) called and can I hide it to get mIRC back to the look it had before I upgraded to 6.3? From what I can see, this new menu provides pretty much the same information that the tabs provide. I know some people will like it and that's great, but I'd prefer to hide it altogether. I realize that I can change the size and lock it, but I would like to just hide it entirely if that's possible.
Of course, knowing what it's called would be helpful as well!
