Quest Givers - Please Go Away!

[AnthonyK]

So, I clicked something and it's showing where all the quest givers are. I mean even the quests i've done already. Just basically the location of every quest giver there is. Please for the love of god, remind my old addled brain where that option was? I literally clicked it and realized.. no I don't want that, and couldn't find out how to turn it back off. Any ideas?
