Ahh, the joys of beta testing! A long time ago, I wrote a program with many interacting subroutines. I tested it thoroughly and knew it was perfect. So I gave it to the XYL to use. She had it locked up in less than a minute! A perfectly reasonable sequence for her had never occurred to me!?
Enjoy your time with the little lab tech!
