Excel 2007 Broken Links - Box With a Question Mark on the Inside

Hello,

I have a client who recently upgraded to Excel 2007. Their vendor
uses Excel 2003 docs with broken links (this is normal for the
application - I don't want to get too deep in to the broken link
problem). Anyway, in Excel 2003 the broken links aren't displayed and
the documents print fine. In Excel 2007 every cell that references a
broken link has a box with a question mark inside. The main problem
is printing these documents. They don't want the boxed question marks
printed - which again, didn't happen with Excel 2003.

Any ideas greatly appreciated!

Thanks,

Jeff
