field function changed comments of MS Word at each formatting action in "follow modifications" mode

When I’m in “follow-modifications” mode of MS-Word 2003, every formating action of the Endnote citations results in “field function changed” marks for every citation from MS-Word, that means all the citations where nothing has changed are commented as “changed”.

That is half a MS-Word question, but may be here are users that know that problem and have found a way to avoid it.
