I run 6 on my laptop (Toshiba Qosmio) and 4 on my deasktop ( old hp) and in IsBoxer i set it up to were they both have a 6 client layout so the repeater and everything works perfectly. Only hassles are no swapping and you cant be clicked onto wow on both computers or repeater regions bug out. and i use input director to make it easy to move mouse from on comp to another.
