Have encountered same problem after installing update to Fences v-18.104.22.168
Window appears saying:
Fences has detected that Explorer was not closed properly.
As a precaution, Fences has been temporarily disabled.
To re-enable Fences, right click your desktop and choose ‘Enable Fences’.
Have tried to re-enable Fences as instructed, but no success.
My system is:
Dell Lattitude in home (non-corporate) environment.
Win10 Pro - version 21H1 (OS Build 19043.1110).
Neither Forcepoint nor Websence are installed.
