What is this called and how do I get it back?

What is this selection thing called, where if you hover around its outside it snaps to designated points, and how do I get it back?  It's disappearing for my mother over and over again, and the only thing I've known how to do to fix it is to get on her computer with TeamViewer and basically delete her SL preferences, then do all her preferences over again by hand.  Yeah, I've gotten a nice pattern formed in re-doing her preferences, I've got it down to 5 minutes now, but still, I'm getting tired of having to do that.

What is this option called, and how do I get it back?

Thanks.

Open up the build menu and make sure that the "snap" checkbox on the right-hand side of the upper panel is checked.

Random screenshot to illustrate:

 

Once it is checked, you should see that compass thingy when manually rotating the object.
