Indeed, that must be it. As soon as I finished the last quest there and went to Dolanaar, it no longer auto-accepts the quests. Phew!
Thanks for leading me in the right directly. I guess it is safe to assume that starting areas are "auto-accept" for quests. With that feature, I wonder why they didn't add an actual option in the menu for this for all quests, as I know that quite a bit of people like quests to auto-accept and use addons to do that.
Blizz is wierd.
Thanks Ethan!
