Actually, what just worked was to use menu command

  Kernel > Kernel Configuration Options

and then use Add and specify Local for the kernel.

Now I can evaluate in 5.2 as usual.

But as soon as I do the first evaluation, I am still getting a 
mysterious sequence of Messages of the form

   Join::heads: Heads CurrentValue and List at positions 1 and 2
      are expected to be the same. More

that I have not yet been able to trace back to a source.
