Selection issue after "upgrade" to Monterey

No, that's not the issue. I can see the menu bar just fine, it's just that when you select items on it, nothing happens. Or in the case of Excel, when you click on the title bar to select the window, then click on a cell to select the cell, the entire window "de-selects". The same as if you clicked outside of the window. Very strange. It's like the x/y co-ordinates of the track-pad are all messed up.

Thanks for the reminder to try Safe Mode, it did not occur to me to try that. That worked, so I got to looking at the tasks that loaded when my system boots, and I saw one called "Scroll Reverser" that I had installed an operating system or two ago to make things scroll the direction I liked. When I terminated that, everything worked properly, and Monterey is setup to scroll in the direction I prefer without the extra app.

Thanks again!
