I finally sorted out 90% of the is+isboxer stuff and I think it's working pretty well. The only problem I'm having now is that my computer has started freezing up at random if I use IS+Boxer, whereas before it wasn't having any problems running 5 instances of WoW at the same time.

Hopefully this'll be an easy fix - I have a post on the IS forms - so I can start making some progress past my fumbling attempts last night to get 5 toons blasting the crap out of jousting targets
