For questions about word documents use a forum for MS Word.
Clarification - The Word document is converted to .pdf and page numbers become invuisble. If i cut and paste them back to .doc document they reappear.
How did you convert the word document? Adobe Reader doesn't create PDF files.
Please post this in the Adobe Acrobat forum if you used Adobe Acrobat to convert the DOC file to a PDF.
Do include all information about the OS and the version of MS Word and Adobe Acrobat used.
