I have the differences for 'id' in the two cases. However, I currently don't have access to
my office during the 'stay at home' order we're having to honor these days.

I don't understand the difference in the 'id' output, but they are different. I showed
the first little bit of each in my first message. Does this help? Should I attach the
complete output of the two runs here?
