Chris, 
Watch for subtle things like 'define's that might not be part of the main
data handling.
My example will explain : We once got error messages on *every* screen
after installing an operating system upgrade - - only to realize that the
system
date had inadvertently been changed to something like February 2020.
We are not (yet) year 2000 compliant and have a defined item in every
screen
to display the date - so each screen was complaining of errors.
