No sweat. I've been using it all day and I LOVE it! I figured out though that there is a small annoyance that you have to fix if you want.
By default, when you're trying to pop a new window, the browser opens a new window in another tab behind the original one. You actually have to set it to make the new window on top by clicking on the little tiny icon in the bottom right that looks like a green arrow pointing to a window. That will "Activate New Window".
Then you are all set!
