Dragging shortcut to unavailable network share when fences running causes explorer process to repeatedly crash

Just purchased Object Desktop mainly for Fences which I used to use on XP.  Installed Fences 3.0.5.11 on Windows 10 pro and rebooted.  Then I created a fence and started dragging some shortcuts onto it.  When I drag a shortcut to a shared UNC folder (e.g. \\servername\folder\ ) that was on a machine that wasn't currently available on the network, The desktop was covered with an semi-transparent light grey overlay and explorer crashed.  It then seemed to get into a crash loop where it kept trying to restart the explorer process but kept crashing in the same fashion.

The solution turned out to be to turn on my VPN so that the machines in question were available, and then I was able to drag those shortcuts without fences/explorer crashing.  It would appear that Fences can't handle failure to access the shared folder.  I see little thumbs in the folder icon showing some of the icons of the files in that folder, so maybe Fences is trying to access the folder in order to generate the thumnails.

At any rate, it would probably be better to more gracefully handle a failure to connect to the target of a shortcut than causing explorer to crash.
