10 Boxing Problems ISBoxer

Hello,I am having trouble when boxing 10 characters with Innerspace.
My setup is 2 computers each with x5 shamans.
The problem is DPS commands eg. Chain Lightning, Lightning Bolt,will not pass to the second team on the slave computer.
So when I target a dummy and shoot with master team 1,everything is normal they all fire on the target,but slave team 2 just stand there unmoving.
The reverse is true when I use team 2,team 1 just stand there idling.
Everything else works such as totems,it seems for some reason the other team isn't picking up the FTL leaders target.
Can anyone help,I can't think of anything else to try?
Thanks in advance:)

Big thanks to Lax for helping me out via the online chat,he got straight to the problem and after a bit of fun learning hotkeys fo copy/paste I had this all running in no time.
Not sure if there are any more 10 boxers out there thinking of running ISBoxer but if you are here is how to solve the problem as suggested to me by Lax.

"-Lax: you'll need to manually set the FTL Follow, FTL Assist, and FTL Target keys in the General key map
go to the first one, hit the * by the target picker in the wow macro action
pick character set #1
it should fill in the "Final macro text"
go to the 3 different keys, and copy the final macro text to notepad
then switch to set 2 with the * and do the same thing
then you need to combine the macros so that the FTL from Set 2 is appended to the FTL from set 1
then go to the 3 wow macro actions, and paste the combined macro in the Commands box
then export, reload ui on all, and it should begin to work."

No problem, and thanks for pasting the instructions here from our chat for others :)

Nps m8 hope it helps :)

I'm having the exact same problem while trying to setup 4 shaman on one PC. Nevertheless, there are some differences since my final macro text is already there and I don't have two sets.

Thank you for any help
