Well, the behaviour is erratic, indeed. Sometimes it works, sometimes
it does not. I deleted the %hide command and then it worked once or
twice, then it didn't any more etc. Could it have something to do with
other notebooks that I have open at the same time? It's a mystery and
obviously difficult to analyse if it is not reproducible.
I put the text version of the notebook after it produced the error
below.
