The new treebar thing is pretty nice. Except maybe a few kinks to work out..

When I have the treebar set to on, and mIRC is unfocused (I have another window/dialog ontop). Then I click on a channel/window in the treebar it will quickly select the new channel/window but then make my current channel/window the active.
So basically it won't switch the channel/window I clicked to the active window..

In the regular switchbar, when mIRC is unfocused and I click on a channel it will make that channel my active window.

Hopefully you can understand what I'm trying to say =x
