@Alan-Kilborn I was also using 8.4.3 (sorry about that).
Thanks for the guidance. I use Razer headphones, and it turns out that it was the Razer software that was causing the problem. Thought I would share in case any other who had the same problem, and like me weren’t smart enough to figure it out on their own.
Also, I’ve used Notepad++ for years (decades?) now, and absolutely love it. Just sent a donation to show my gratitude.
