If your system is Windows then check for any driver specific settings/options under "Mouse" in the Control Panel.
Recently changed my own laptop trackpad scroll settings from there for same reason.
Otherwise the trackpad may have a specific management app you need to run to access those settings.
I have a Mac and I made the trackpad change when I purchased it.
However the LR and PS scrolling does not work that way, that is why I thought that there may be a menu item in LR to do it.
Both LR and PS takes whatever the OS sets the scrolling to be.
So I don't know what you are experiencing.
There is no problem.
I just would like to reverse the direction that the fingers go when using the trackball.
Another words, the normal way (Natural) when I scroll my fingers up on the track pad the screen goes down, I want to reverse and have the screen go up when I scroll up.
I haven't used a Mac in a couple of years and when I did I found the Apple Natural scrolling completely opposite of the way I think. So one of the first things I did was set the option to reverse the scrolling. IIRC this reverse option changed the TP behavior system wide for every program.
To my knowledge, and I looked, there is no option in either LR or PS for scrolling direction. At least none I could find.
Thanks, I will keep asking, maybe you tube may have something.
