excel 2000--- I use the same workbook for years, once each 2 weeks. It
contains userforms and many macros. I used it yesterday and saved it as
usual without problem.

I worked again with it this morning and tried to save it but a microsoft
message occured -- Document non enregistré-- (document not saved)

What did occur ?
How to correct and be abled to save the next time
