This code is causing a workbook to throw the error "Document not
saved". Oddly enough it saves fine once I remove it. How can a message
box cause such a problem?

It gets stranger....If I create a new workbook and paste the code in
there it saves without a problem. The original workbook has 11 sheets
and a decent amount of data if that matters, (which I don't think it
does). Is this some kind of fluke bug or is there an explaination?
Excel 2k3, SP2
