Thanks; I had looked at that already: the Protection menu lists four items
but the first three are not available (Protect Sheet, Allow Users to Edit
Ranges..., Protect Workbook); the fourth item is available, Protect Shared
Workbook, and that is not selected.
Anything to do with the fact that this is a Shared workspace? Just answered
my own question....that is the problem...Delete Sheets is one of many
commands disabled when the Workbook is set as Shared.
Thanks,
