Content Library content suddenly missing

Boorsman

I had a scene opened and while I was working on it, everything in my Content Library went missing.  I have no idea how this happened.  Perhaps I hit something by mistake.  I cannot figure out how to get it to show up in my Content Library.  Anyone have any suggestions?

Above "None" and below the search box in the middle of the bar there are two rectangles - click the lower one to re-expand the folder list.

Thank you, Richard Haseltine.  I probably would have never noticed those two rectangles.  I thought I somehow deleted all my content.  Boy am I relieved that that didn't happen.
