That's what I was looking for - confirmation that is in somebodys
processing queue. Thanks Carsten.
Unfortunately I can't hel as I have barely the elisp knowledge to
maintain my .emacs file.

Yup - exactly. That would be the best solution.

Possibly because I am using the mouse most of the time to navigate in
text and select buffers, I did not realize this.

Tried briefly and it seems to work:
1) the visual overlay stays there upon C-x s from indirect buffer
2) If I click with the mouse into it, I am redirected to the indirect
buffer (correct terminology here?)
Let me know when you pushed it to git, than I can upgrade again.
Thanks,
