Suggestion/Bug
I use a VPN between several computers. If a fence contains a shortcut to another network drive, folder, etc., and the device is not connected via the VPN (the VPN program has failed to load, the target computer is off, etc.), hovering over the Fence header will cause the computer to lock up and Explorer will crash. Explorer usually comes back, but there is no way to get the fence to roll down without disabling the program. However, if the same shortcut is on the desktop the computer will boot up fine. The problem also occurs when dead shortcuts are put in fences, in cases where an IP is no longer active. Windows 7 & 8.
