Today my PC woke from sleep mode and the icons on the desktop and within Fences were larger. I tried rebooting and reapplying a previous Layout snapshot but that didn't fix the issue. I was able to correct the issue by right clicking on the desktop, selecting view, and then Medium icons. I don't remember having the icon size selected in the past, just used the default icon size. Did something recently change with Windows 10 to cause a conflict with Fences?
