I've been using SDL Trados Studio 2021 for a few weeks now and I found this strange mouse scrolling behaviour in concordance windows. When I want to check if a term has already been translated, I use a key combination to look it up in concordance. And when I click inside concordance window (no matter source or target results), scrolling doesn't work. I have to click again in another window so works, i.e. if I clicked in the left windows, I have to click again in the right window and vice versa. This issue doesn't occur in Studio 2019 so I guess it's not a hardware problem. Does anybody know what might be the reason?
