No.

Do you mean like after you completed the MQ? Or when you are doing something else then the MQ, but still havent completed it?

I can confirm they do. I was on the way to a quest location, saw what I now know as a Dragon Head icon, went to explore....and a dragon attacked, found a dragon wall after the fight, wasn't able to use the shout though....hope I didn't need the word before killing the dragon, that would be lame.

Clear and unambigious, thanks.

i was making an iron dagger in riverwood, when i saw a huge shadow fly over. Lets just say, the villagers had quite an interesting day lol.

lol

Yes.

Thanks for the more precise answers.
