Thanks for the quick response!
While I normally do not install Beta versions, this time around, I followed your advice and installed the version of Fences you linked. Even though the thread is entitled “Fences 4.10.06 Release Feedback Thread” it is, indeed, version 4.11.
Unfortunately, the problem still persists: upon re-boot, portals are still not populated with icons.
I also have another problem that is also mentioned in the thread you linked:
Right-click Desktop ==> VIEW ==> CONFIGURE FENCES does absolutely nothing.
To actually configure Fences, I had to create a separate shortcut on the desktop.
(I have had this problem on both of my Windows 11 machines. I just did not mention it before as I wanted to get the “Empty Portals” problem out of the way first)
