This just started happening today. I have Folder Portals on my desktop. A double-click on a subfolder icon would open that folder in the current fence, but it doesn't work anymore. It always opens a Windows Explorer window to the subfolder. I have turned off 'Allow Navigation' for the Fences and turned it back on and it doesn't make any difference.
However, if I right-click on the subfolder icon, and select 'Open', it opens the subfolder within the current Fence just fine!!?? As it should..
I have rebooted several times, and uninstalled, rebooted, reinstalled and it still does the same thing.
I have Fences v18.104.22.168 from Steam. Any help is appreciated.
