Instant 3D Not working

I just watched a video on using the "Instant 3D" feature. I replayed 7 times. Mine is not working as the 2011 video shows. I also searched out the SW Help pages. No success there either. I want the circle to go in and out. But only the entire raised portion is moving in and out.

Who can explain what I'm doing wrong ?

Thank you.
