Cant make SPIN work in Blender 2.27

Support Basics & Interface
1

I am unable to make the Spin button work in 2.27. I make a mesh, exit Edit mode, select the mesh, set spin parameters (360 degrees, 21 steps) and hit the spin button, but nothing happens. Am I leaving out a crucial step? Have others encounter this problem?

Thanks

You can only spin selected vertices in edit mode, with your cursor as the center point.
