Pete,

   Ah, now I see it. When I click on either in the object inspector I see no
indication of the problem or its location. Nothing changes in the
application window. I search the Qt5 and PyQt5 manuals for 'no parking' and
find nothing.

   Where is this documented so I can learn how to know why it's displayed and
how to respond.

Much appreciated,

Rich
