I have been continuing to follow posts on this topic. On another computer 💻 that I own, that also is on the Fast Track for Preview releases of Windows 10, there has never been a crash of Fenses and it did not crash after being updated to the lastest Preview release.
On my regularly used PC, it crashed again today - prior to when I installed the latest Preview release. What I never mentioned in any of my posts about this problem was that even though Fences crashed, it left most of (but not all of) the icon shortcuts where they would have been had Fences operated correctly! This time, after using Revo Pro and deleting all leftover files following the built-in uninstall, I reinstalled Fences 3.1 and one at a time, moved the appropriate icons to the Fences I then created. No sweat 💦. It worked.
I updated Windows Preview and Fences continued to work. All in all, a very strange acting bug 🐛, wouldn't you say?
