Use the worksheet Change event on the "setup" worksheet to set or clear a
global navagate_allowed flag.

Use the worksheet Activate event on all other worksheets to check the flag
and kick the user back to "setup" if the flag is False.

Is it possible to use the act of navigating to a different worksheet as an
event in VBA programming? For instance, if I had a workbook with multiple
worksheets, and the primary sheet that is displayed when the workbook is
opened is called "setup", I want to make sure that you cannot navigate to or
view any other worksheets until all necessary changes are made to the setup
worksheet.
