New to Multiboxing, Slave continuously moves farther away

I was wondering if I am doing something wrong or if there is a setting I can adjust to make my slave stay closer to me. When I log in I can see the slave making the exact same movements as my main but as I move around it moves farther and farther away. Is there something I can do to fix this?
