Thanks Sven-Ingvar,

Thank you for the link to Gary's guide on XaraXone. I hadn't looked there.

Unfortunately this 'trick' seems to work for left-justified text only.
At least, I could not get it to work with fully justified text.

So, I fear that the question remains open:
How to wrap (fully justified) text around an object?

Hints are welcome.

Stephan
