if you are using keyclone to launch your wows and route the keys around, that is all it will do. it has no interaction/control/influence with the network bandwidth.

check to make sure you have enough bandwidth for the task... along with your latency. if its too high, or your cpu is totally pegged, then it is quite possible the 3rd wow is being starved for cpu cycles.. and in turn, could be missing out on network packets.

try launching them without keyclone running. my guess is that you'd have the same issue. if so, consider 1) more memory or 2) a better cpu or 3) a better grfx card
