adding a target frame to a hyperlink

Version: 2008
Operating System: Mac OS X 10.5 (Leopard)

I have a Word do***ent that contains hyperlinks. The hyperlinks include a
target frame. When I Save As Web Page, the .htm file contains the
hyperlink but not the target.

Looking at the Word do***ent in Word 2008 on the Mac, the field codes look
OK. I've links originally created using Word 2003 on the PC with the Target
Frame button:

{ HYPERLINK "http://www.foo.foo
<http://www.foo.foo>"
\t "_parent" }

And, I've links that I've created in Word 2008 on the Mac:

{ HYPERLINK "http://www.foo.foo
<http://www.foo.foo>"
\n }

When I use File|Save As Web Page, both of these HYPERLINK fields generate
hrefs missing the target:

<a href="http://www.foo.foo
<http://www.foo.foo>">http://www.foo.foo</a&gt
<http://www.foo.foo</a&gt>;

Is there a way to have the generated HTML preserve by target frame?

Thanks,
Heidi
