To your 3 questions I answer:
1-No. The instructions seem to have done nothing. My current version is: 5.86 (Revision 8).
2-Windows 10 Edition - Windows 10 Pro - 64 bits Version 22H2.
3-Windows Defender Firewall.
By the way, I have a suggestion to make.
In each window (FENCE) I try to place the shortcut icons organized in rows for each application, and that means having rows with different numbers of icons,
but the program alters my arrangement because it insists on filling the rows to the right limit.
Thank you for your attention and congratulations for such an excellent and useful program.
