Yep, Blizzard have found the problem and have fixed it, but it's not known when it's going to be implemented. I have found that if the followers WoW client is minimized it will not disconnect, but with a minimized client I can't broadcast keys and actions to it so it's useless.

Some people have reported that enabling v-sync fixes it, and some have mentioned that Checksum Offload disabling/enabling takes care of it as well, nothing has worked out in my case


If anyone has a real WoW client and you get hit by this (sold my previous, back on a couple of trial accounts), can you enter the PTR server and /follow someone to see if it's still in?
