I started learning my skills first, then entered the world. A lovely quest log popped up with lots of things for me to do! I just picked one quest, then tried to close the dialog box. It closed and popped right back up! I tried agreeing to all of the quests in the log and then closing the box, but it still popped up! I was able to move the quest log around but when I'd close it, it would pop back up.
after saving and closing the world: no more quest log. I was able to then open and close it without the error. Problem solved!
I'm viewing glitch through firefox 3.6.8 on windows xp.
