It is not the double click thing. I've turned that off.

I wound up having to create a new fence and instruct the Fences software to place all new items into that Fence. If I don't do this the new file, when save to the Desktop, will briefly appear on the Desktop and then it disappears despite still being on the desktop.

That option does not show up when Fences is installed.

The issue isn't that no icons are showing up. The issue is that new icons don't show up. Fences will display them and then they immediately disappear.

Shortcuts and files that were on the Desktop prior to the installation show up fine. Its the new ones that are disappearing.

Something is screwed up with Fences that is causing this issue.

I turned on "Align Icons to Grid" and the icons magically appeared from off the screen. I have no idea where they were hiding.

I think that issue is self-resolved.
