Lost Visual Selection Reference

[TheCADWhisperer]

I was working through the Hair Dryer tutorial when I stopped for a while to eat lunch.

When I resumed work I could not get any visual reference (on the part) that I was selecting an edge (or double click selecting), but continuing the operation it did appear I had selected the edge (dialog box indicates I have in fact selected 8 Edges).  (see image)

Rebooted the computer and all worked again as expected.

Not sure if this is a hardware or software problem.
