You get this particular message only when you open a workbook that was
already fully calced (as far as the earlier version of Excel was concerned)
but Excel 2000 calced it anyway just because it was from an earlier version.
To stop this you need to make a registry entry (Start->Run "Regedit" (no
quotes)).
Under:
HKEY_CURRENT_USER\Software\Microsoft\Office\9.0\Excel\Options
create a new DWORD item named: FullCalcOnLoadOldFile
Leave its value at the default of 0.
Note that even after this change if the workbook was not fully calced, and
you calc it, you'll get the usual "save changes" prompt.

Note: In Jim's instruction, he refers to Excel 9.0 which is 2000.
Excel 2002 is 10.0........Excel 2003 is 11.0.
Same fix applies.
