How can I disable the new built-in PDF-viewer?

more options

Hi Folks,

I recently got a strange problem with Nightly 15.0a1. All PDF documents are opened with the new built-in PDF viewer and it does not matter if it´s enabled or disabled - it just always opens and renders/loads the PDF file. But I want it to be done by Acrobat Reader, or save it to disk. I tried Tools-->Options--->Applications and marked all PDF related stuff to "ask" or selected the Acrobat Reader, but it did not help at all.

Can anyone help me with this?
