All the recent instances of a missing clock I have had have been due to
various misconfigurations and coding errors while developing another clock.
Everything seemed to be mostly in place with 0.11.0,
with the single exception I note that you might want to consider hard coding

into the point where we close the settings dialogue so the
system has a chance to reload whichever script it is running.

Or not - I am not a python programmer until yesterday

Looks to me like it has arrived -
Where do we vote it into extras-testing?

The only caveat I see with this program is if a person
uses 'display seconds' (which I do always) and there is any kind
of issue with the particular clock (which I have done in trial and error)
is that it can get interesting - but that is merely a self-inflicted problem.

Cheers.
