Dear James,
No need to use strong language like in the answer I received below. Some
of us are occasional users (thanks Bob for the apologising email).
Furthermore you had all the info to solve the issue, see below.
Clue:

Question: Is there any trivial (or less trivial) explanation to this

Thanks for your help,
G
