Hello again,
Did you read the steps listed there? Reply#47. It does not talking about re-installing it just talking about if Fences keep crashing. Your symptom where you mentioned
Fences 4 continually refreshing my screen, blanking icons and making my system unresponsive
That showing to me that Fences 4 is crashing and restarting. And one the reasons we found out from various user is that there are cases when there is one or more shortcut on your desktop that link to network drive or cloud shares. Fences will crash if that link is broken or the network not available. Using that steps mentioned on that reply will identify which shortcut is having the issue.
Thank you,
