My apologies for the lack of clarity in my post. I will try to make my issues clearer.

When i get my master to target an NPC for questing, or I attack something i cannot get the slave character to assist. I have a macro set up on both accounts, i have positioned them onto the same buttons on each screen, but when i click it on my master, the slave is unresponsive.

The only way i have been able to do this is by clicking on both screens.

I am also using Jamba and i can get the slave to follow the master from the master screen, but that was all.

Also, i needed to do a quest where i was required to pick up so many of an item, i guess the workaround for getting the slave to do this will have something to do with click to move and IWT, but i cant get that going either.

The click to move and the IWT works if i tell the slave to do it on his own screen, but if i issue the command from the master screen, again, he is unresponsive.

Then the only necessary step would be to bind a key (one that is also set to be broadcasted to your other window) to "Focus Target"
I have done this, i set my button to "]". When i use it, the master interacts but the slave does not. I also added the bound key into pwnboxer

Then target whatever on your lead toon, press your Assist and follow that up with your Focus Target bind.
This is my main issue, i know it is supposed to be easy and straight forward which is why im going crazy because it wont work, im sure ive done something wrong somewhere, but i just have no idea where.

Thanks for your time guys
