Ok, I will send some screenshots, most likely tomorrow. I'd rather avoid
to send them, but it seems the fastest way to explain.

I do, the person I was discussing this issue with, however did not. He
still uses 24. But he was also bothered by the paragraph direction. For
example OO (OpenOffice) whose BIDI implementation does not seem to be
perfect, only changes the display paragraph wise. But I will elaborate
an example.

Ok, I realize that there is something, but for me that is to tiny. I
will try your advice.

Thanks again
