Err, what? The whole point of MDI is so that you can segment information into proper windows. It's exactly the opposite of "needing to display everything in the active window". MDI allows you to NOT have to display everything in one window. This is the reason why mIRC is an MDI application. If you don't like that, then maybe mIRC is not for you.
MDI isn't an mIRC issue... it's a Windows issue... MDI is basically windows organized within another Window.
