Creating web pages using MS Word

[CMO]

Hi,

I've created an internal web site using MS Word and have been discovering
more and more problems when I save. When I create hyperlinks to documents
and other pages I am not putting in their exact location, rather using
relative links which enables me to move the structure around different
environments without having to change the links each time, eg:

.../<FolderName>/<Filename>.<Extension>

When I save this it automatically reverts to:

...\<FolderName>\<FileName>.<Extension>

Normally this is fine, but I have now incorporated a search engine which
cannot understand the ..\<FolderName>\<FileName.<Extension> and needs to see
.../<FolderName>/<Filename>.<Extension> in order to search properly.

Is there any way I can stop Word doing this every time I save?

Thanks in advance from someone in crisis!!
