This is very irritating...I need to be able to find a resolution to this
problem.  The Excel workbook simply contains Named Lists that I need to have
working.  When this error occurs (seems random), I lose them and my workbook
doesn't work anymore.  (I am forced to answer 'yes' to the question:
"Error found unreadable content in 'cosapa.xlsm'.  Do you want to recover
the contents of this workbook?  If you trust the source of this workbook,
click Yes."

I have to go back and recreate them until this happens again.

I desperately need help or assistance in order to fix this...............
