It does work, it just doesn't show on first window.
As I sometime have the memory of a goldfish, I do tend to need checking several times what quest I'm currently doing, and where I am in it.
So going to the 2nd window is an inconvenience, as is the fact that not showing in the first one tends to bring me to think I don't have one running...
As I said, some times goldfish memory
