I dont beleive its ever displayed in the active window, but rather in the window it was called from.

to produce the same effect you want.,

click on the icon in the top left corner of the #test window, then select editbox, then enable editbox, finally take the bar intersection the type in box in the channel and drag it to the far right as it well go. Scrren now looks pretty much like it used to, except for the small bar on the right.

Now add this remote.

on *:JOIN:#Test:{ .timer 1 0 editbox -no $chan $editbox($chan,1) | editbox -no $chan /whois $nick }
