I have a client that has a PowerPoint Presentation, with charts and linked
workbooks. The excel workbooks in turn have formulas referring to other
workbooks. When you open the PowerPoint presentation, you need to update the
links to get the most up to date information.

What is happening when the links are updated, is:
It opens the Excel File
It asks if you want to update the Excel links to other workbooks

If you choose no, the same message box opens in an infinite loop
If you choose yes or update, it clocks and then says one or more links
cannot be updated, and then asks whether you want to continue or edit links.
Continue loops back to same questions
Edit links brings up links dialog box, but when you edit them, they loop again

Reviewing the Excel file, I have deleted the named ranges linked to files in
temp folders, and those with REF in the links.
I also checked the charts, and made sure they were referring to ranges
internal to the workbook.

THe problem still occurs.

Any ideas what is causing this to loop? Any ideas as to a solution?

Thanks in advance for ANY help you can provide.

He is using Office 2003.
