Where is chamfer pop up?

It used to be that the chamfer tool worked the same way as the fillet tool in that when I activate the tool and click on one edge of a model, a pop up came up.

Now when I activate the chamfer tool, no pop up.

Have I messed up a setting somewhere or has this pop up been eliminated?
