Needing help - **CHEAT** and ISBoxer

Hey everyone,
I have spent around 5-6 hours banging my head against the wall trying to have 4 instances of D3 up and running, with **CHEAT** running on my main window. The errors I continually get, is that when I load **CHEAT** up, it keeps trying to target the windows that are not my main window, meaning it wont work.
Could someone kindly please assist me here in getting this to run correctly?
