cs6 - How to access the rotate by angle functionality of Illustrator's Rotate Tool

I read that when I select the Rotate Tool (R) in Illustrator CS6 then Alt + Click on a point to select the rotational reference, a dialog should popup prompting for an angle. When I did that nothing happened.

Is there supposed to be a popup dialogue, or is this a bug? How do I make it appear if there is one?

I am trying to follow a tutorial and got stuck on this step.
