Does anyone have any suggestions on how to create some sort of obvious
indicator/reminder (other than on the Excel window header) that states that a
workbook is currently in "read-only" mode? The idea is to prevent someone
from forgetting that the file is "read-only", making a bunch of changes to
it, only to later realize that their work can't be saved (without doing a
"save as" a different file name). i.e. a message window that appears when
typing?? watermark?? etc etc??

Thanks.
