I started a new discussion 'The chicken and the egg, which came first?'. As I
pressed Commit, and the screen cleared, a little 'joking' text showed up
briefly in the top lh corner before the next screen was displayed. I did a
reply and on pressing 'post reply', a small panel opened. I inadvertently
closed it instead of maximising it. I pressed 'post reply' again and got an
error which made reference to 'joking' (see screenprint).

Later I tried to add a learned 'woof woof' reply to the chicken & egg
discussion and again got the same error.
