no "Advanced Tools" options...

I realize by reading other posts that I'm having problems with the "advanced tools" options that others have had as well on imovie 11. Although I'm still waiting for someone to respond on other posts I thought I'd put up my question anyways.

The Problem:

The "advanced tools" option is definitely ON, but when I try to drag a clip on top of another nothing happens. According to many videos on youtube and support videos from apple say a pop-up menu with (pip, cutaways, green screen, etc) should come up, but I've tried several options and nothing seems to work.

Has anyone had the same problem and figured it out?
