Thanks for your reply.
I noticed and studied this already.
Its valid for all Tabs - except the "File"-Tab (the most left one, I have a german surface)...

Thank you, that makes everything clear. But it was not obvious for me, that the purpose of OCRring in pdf xchange was only searching and highlightind and so on. I assumed, it was completeyly editing after performing ocr. Perhaps it could be something to be made more clearly on the web page.... Thank...

I need to eliminate the "save" and the "save as" possibility.
All users must "save" documents by printing them to a pdfprinter, which automatically makes pdf documents in the needed format.
But I didn´t find a solution how to change the "file" menu....

If I OCR a scanned document, the new document has an OCRred layer with the original image as an overlay. So if I export this file for example to word, I cannot work with this document, because also in word I have the scanned text (unvisible in the background) wth the original document as an overlay....
