When selecting features the Digitizer Tool is not selecting anything, only select by polygon works

I have a workspace with line and area layers.  Today for some reason the Feature Info Tool (Circle with i) and the Digitizer Tool (pencil) cannot select any features.  But when I use the Select by Drawing Polygon tool, it can find all of my features.

So I must have inadvertently changed a setting but I cannot seem to determine what setting and how to get the usual behavior back.
