Ok. Strange enough, now on the morning when I started a brand new
instance of POV and tried to reproduce the problem, it has vanished. I
assume the minimization of the scene file might have caused that, since
with more complicated files I have had similar problems systematically.
Or then beta 4 already has different behaviour compared to 1 and 2 in
this case.

Ok.

In fact, I used it originally, but I removed the autostop directive when
minimizing the scene file showing the bug. Using or not using the
autostop didn't seem to have any relation to the bug appearing or not
appearing when I was able to reproduce the bug at all...

I think this is Murphy's Law or something, that the bug that has annoyed
me for weeks now disappears as soon as I start extracting it :-).
