Hope everyone here is safe and well!
I see some other posts related to my issue, but most are more than a few years old.
I believe the issue started with v3.01, but have not tried rolling back yet.
I am having this problem on a machine still running Win7 x64.
All toolbar functions and their respective File menu commands work, except for Change & Add Directory.
I tried installing v3.01a on another Win7 x64 machine and everything works fine.
No doubt this is some kind of Windows issue, and considering Win7 is EOL, I don't expect it to get looked into. However, I'd like to see if anyone else has experienced this and and has any direction.
