I have been using Fences 3 and 4 for many years, with few, if any, problems, although I don't often create new Fences. However, when I recently created a new fence in Fences4 I was unable to sort the shortcuts. The 'Sort by' menu had 'None' selected, but clicking on any of the options had no effect. Moreover, I could not delete the newly created fence. I opened one of my previously created fences which was sorted by Name, and found I could not sort by any other criteria. This fence had a ticked 'Maintain sorting' option, and I could not deselect it. The 'Sort by' option on the Desktop Context menu works as expected for items which are on the desktop but outside a fence.
I fully uninstalled Fences 4 and ran the purge fences batch file, rebooting at appropriate points. I downloaded and installed the trial version of fences 5.88.8. and created a new fence for desktop icons. I could not sort them nor delete the fence. I restored a recent snapshot from a backup of my Fences 4 data. The restored fences still could not be sorted by different criteria.
I installed version 5.88.8 in a new Windows sandbox and also in an older Windows 11 Hyper-V VM. In both cases, they worked correctly.
Please can you advise how to make my fences sortable and deletable again?
