The issue for me isn't scrolling left or right across columns, it is scrolling vertically in a column that is several columns to the left of the last folder viewed. This is also sporadic, sometimes it works but most of the time it doesn't. I haven't determined the trigger to failure, but any time it won't scroll, if I click in the left column I want to vertically scroll it lets me scroll there. The bug is that I shouldn't have to click first. It was never required before Monterey and it isn't always required now. For example for some reason, I was just able to scroll vertically in column 2 when I had folders in four more columns selected (plus 5th column with documents in it). I closed finder, then opened it again, navigated to the same folder, scrolled left to the second column, and when I tried to scroll down in that column the screen bounces back to the far right column. It is a defect, no way this is a feature, and if it was the use case is rediculous because it breaks prior useful user experience for no rational reason and is inconsistent.
