Upon further checking. I did not have the latest version of ISBoxer. I do now.

` still works to target my main window character and follow him after I imported from ISBoxer the set up Riiker sent me.
When I target a target on my main window and press F6 it says "Target has no target" on my main window and nothing happens on my second window. When I click to my second window while my first window has a target and my second window has my first window character selected and hit F6 he does acquire the target my first window has as a target. So it appears the F6 key works, but only in the current window. In ISBoxer it shows that Acquire Targets Target is supposed to be All w/o current, but that seems to not be happening.
