When I start a game and go to chat, a dialogue box opens with chat messages from the previous day. If I want, I can select one and it will chat that message. It is not something I want. Even if I delete saved chat (in Chrome settings and also delete the entries in the dialogue box), all it does it make everything fine for the rest of the day. But when I log in the next day, I have a message or two from the prior day to delete. Anybody know how to turn off the setting that saves chat? I asked BBO and they clearly had no idea. They just sent me links about deleting what had been saved, not about how to stop saving.
