I have been multiboxing for about 3 years now and have never had a problem with my assist.
I am using ISBoxer
Whenever I try to make my slaves assist it works for the first 5-10 trys then the slaves start targeting a random slave
I have never had this happen before and was wondering if there was a fix.

I have tried using keyclone, and a few other broadcasters and i keep getting the same results.
