Windows 8.1
Infix Pro 7.2.5 Trial version
A large document of 250 pages had 50+ bookmarks in it. These had been added by hand in Infix, as well as in other software.
The document was created by scanning pages from a printed article.
The hyperlinks all worked - clicking on them correctly jumped to the asociated chapter/section.
The document was saved, and could be opened again, and the bookmarks still worked. They worked in Infix, and in two PDF readers.
Then, after OCR recognition was run in Infix, although the bookmark text remained, the hyperlinks associated with each bookmark were removed, so I can no longer click on them and go to a given chapter/section.
I saved the document before I realised, so I have now lost 50+ hyperlinks.
