Since Windows 10 Build 10130, there is a phantom button on my secondary monitor's taskbar with no text but a File Explorer icon. The preview shows a blank black screen; clicking on it does nothing. It doesn't appear on the primary taskbar, and if I turn on Windows' built-in secondary monitor taskbar, it doesn't show up there; only on the DisplayFusion taskbar. It turns up within a few minutes of booting, and nothing seems to get rid of it.
What I did was to right click on the icon then select 'Move To Next Screen' and it disappeared. It comes back on a reboot but as for now its a work-around.
I noticed that on my machine yesterday as well but didn't have a chance to look into it. The next time it shows up here we'll investigate further and hopefully get it all fixed up
I notice that when I use Alan's fix, a phantom "move to other monitor" button appears on my primary monitor. When I hit it, the phantom button then reappears on my secondary monitor.

Just noticed that today as I changed my dark background to a light one.
And....
If you right click and select Move window to system tray then that what is does but if you right click it in the system tray no matter which option you try to choose, it will disappear when you mouse over it.
We've just released a new DisplayFusion beta version (http://www.displayfusion.com/Download/Beta/) and this issue should be all fixed up. Please let us know if you run into any trouble after updating.
