I received a .docx file from a colleague with comments added using the 'Review/Comment' feature in MS Word. I need to convert the document, including the comments, into a PDF, but when I use the 'Export as PDF' option in LibreOffice Writer, the comments don't appear in the PDF. I've tried checking 'Export comments' in the PDF Options menu, but it still doesn't seem to work. Is there any way of fixing this? I'm running Ubuntu 12.04 with LibreOffice 3. Would it work any better with OpenOffice?
