Laws of physics in reverse?

[Philippe Errembault]

It's probably the local leprechaun. Leprechauns behave positively when
properly fed, but if you forget to feed them, they will act like gremlins.

In regard to the suggestion of using glue, I would just suggest that there
are glue designed for that kind of use (i.e. it is still possible to unlock
it)... Opticians use that kind of glue, and I remember that locktite made
such a glue... (this is a general observation, since I'm not competent (yet)
in the specific field of pianos)
