Cross references are not working correctly when used in a list.
1. Create a list of at least 3 items and assign a Heading to each.
2. Place your cursor in a blank area of the document and cross reference each of the headings.
3. Convert to PDF using Acrobat X.
Result: The first and last item in the list do not link but the rest of the list links correctly.
Note: Word 2003, Windows XP, Adobe Acrobat X.
