I have this problem several months now and it is really annoying.
When I first login I cant whisper anyone at all. The game doesnt change the chat box to the whisper function. And it doesnt matter if I do it with right-click or /w .
Than after around 10 min all whisper contacts I tried to choose earlier pop up after another. Which is another annoyance….. Because everytime it activates the Chat window so I cant play….
I hope this can get fixed
