Thanks, but that doesn't solve my problem:
The "use internal viewer" checkbox was unticked all the time for PDF. When I wrote that pdf books are opened with calibre I mean that they are opened like with any other external program, just that the external program is calibre itself and not my PDF viewer "Okular".
