I'd still think user error--even if it were unintentional.

I am working with a shared workbook in which only a few administrators have
accress to the files. Recently several worksheets have been moved or deleted
from a particular workbook whcih conains perhaps 50 worksheets. No one has
anything to gain from deleting the worksheets and we have ruled this out. I
am wondering if anyone has input as to what may have happened to them. Is
there a virus or worm that might delete random worksheets in a workbook. The
worksheets were not cotingious.

Thank You
