GOD bless you Sir!!! 
IT FINALLY WORKS!! I don’t know why, but I had to run the process 3 times before I could get the desired results.
1st time: Jog Wheel wouldn’t move at all.
2nd time: Jog Wheel would ONLY turn left. This was an improvement, as the wheel was turning left and the tracks were scrolling left. But I got no movement at all when I turned the whell to the right.
3rd time: I started documenting each step in a series of screen shots to prove that I have followed each instruction. But then it started working in BOTH DIRECTIONS correctly! So there was no need to post the pictures.
I am soo glad that you were able to repro the “opposite scroll process!” Nobody else even acknowledged that this was the case. So getting back even that much information was reassuring! Now that it finally works, I feel such immense relief and joy. This thing was bugging the crap out of me! Thank you, thank you, THANK YOU!!!
