As a user myself, I think it is best to upgrade Fences to Version 4 if you is using Windows 10 or Windows 11 latest version. What you can do is, do Fences 4 free trial and see if it work for you.
basj is correct. I've used Fences 3 an 4 on Windows 10 and Fences 4 was far superior. On W11 I've only used Fences 4, and it's great.
