Problem solved! Many thanks to Jean, Carl and Han-Wen for providing the solution.There is a new OOoLilyPond release: <https://github.com/OOoLilyPond/OOoLilyPond/releases/tag/v1.1.5> Only for LilyPond versions 2.23.5 and later, the new options are inserted into the command line call.Nothing else has to be changed. I'm happy again. ;-)Cheers, Klaus
Thanks for the new release! Seems to work out-of-the-box here :-) MT
