A bit more clarity ...

So there seems to be NO BUG.  It's just an odd transient behavior which I now noticed only because of tracking "time" on some small tasks.

Definitely not worth touching brittle code.  "It's just how it is."

And that's ok!  :-)

Thank you for your attention to this matter which now is clearly smaller than expected.

No, no, not clock check mode.

Ok. Got it.

I looked into the code, and I do have a feeling that it is brittle
(agenda is a very old and convoluted code), but without a concrete
reproducer I wouldn't dare to touch it.

I hope the screen captured images came across in the previous email?  
They should help explain.
I indeed did not notice the attachments - they were not indicated in the
plain/text part of the email. They indeed did help to explain things.
