MS Word and bookmarks

[Maggie]

Hi all
I am trying to insert a rtf bookmark into a MS Word document and get it to automatically update.
Steps taken

Select package in project browser
generate a rtf document
Right click on package -> Documentation - > Copy RTF bookmark

Open MS word
Insert file
Select RTF File produced above
press Range
Paste in the bookmark copied in EA
Insert as Link
[/list]
This results in the correct MS Word document.
If I now change the package in EA and the regenerate the RTF document the changes are not reflected in MS Word.
I have the update automatic links on open select in MS word

How do I get MS word to update its links?

TIA

Maggie
