....ups.....

I changed the setting to "enabled" by my own. Apparently completly wrong assumtion, that this setting does not cause any problems.
Meanwhile I imported/changed (outside MS)/reimported...... some test pdfs and now I know what this setting does.

But - if I´m honest - I don´t understand really the meaning of this setting,  just better "unchecked".

I´ll do further trials......maybe I´ll get it,.... sooner or later.....



Thanks again for this hint!
