I have document which has a number of cross-referenced figures, bookmarks,
etc. Also on one of the pages is a linked Excel spreadsheet object.

For some reason, when-ever I click on a cross-reference anywhere in my
document, I get the following dialog:

-------------------------------------------------------
'[file path]\Excel Linked File.xls' contains macros.

Macros may contain viruses. It is usually safe to disable macros, but if the
macros are legitimate, you might lose some functionality.
(Disable Macros) (Enable Macros) (More Info)
-------------------------------------------------------

I dont' mind this dialog which is related to security settings when I update
my links manually, and appears since there are macros in my excel spreadsheet
file. However, I don't see why the field of this particular object must be
updated everytime I use a cross-ref in my word document which has nothing to
do with the spreadsheet object.

Any ideas what is going on and if there is a way to prevent this?
