I created a document by word 2010 in which I inserted captions for pictures and cross reffernec. I saved the document in my computer and emailed it to a colleague. When she opened the document in her computer, the caption list ( numbers which were cross referenced to pictures ) was not avaiable and she was not able to add refference to a picture or change an existing cross refference. It seems that caption list is only avaiable in the computer which the document is created.
