Thanks.

OK, now I am only seeing failures for the following sequences of
commands:

  demo plotyy
  demo quiver3
  [...]
  quiver3 example 1: failed
  get: invalid handle (= -1.45621)Press <enter> to continue: 
  quiver3 example 2:
   [x, y, z] = peaks (25);
   surf (x, y, z);
   hold on;
   [u, v, w] = surfnorm (x, y, z / 10);
   h = quiver3 (x, y, z, u, v, w);
   set (h, "maxheadsize", 0.33);
   hold off;

  Invalid call to any.  Correct usage is:

   -- Built-in Function:  any (X, DIM)

Oddly,

  demo stem
  demo surfnorm

and

  demo stem3
  demo surfnorm

appear to work correctly.
