modifying files created from older versions of Excel

P

Patriot

All my users running Excel 2007 are getting errors when trying to modify
Excel Spreadsheets created in older versions. When they open the file the
heading includes [Compatibility Mode]. They immediately get an error, Excel
shuts down and Excel attempts to recover file.

I have tried applying all MS Office updates to no avail.

Thank you for your assistance.
