Mouse-over Hilite How do I turn on-off?

Somehow in my haste I have inadvertently turned off the mouse-over hilite.

Things used to hilite prior to selection as I moved the mouse pointer over them.

Whether for sketching, measuring, drawings whatever.

Now.... nada.

Have looked thru Options but can not find a setting that makes sense to me or works!

I'm sure this is a basic easy thing (like many, once you know!)

Please help.....
