I am having a problem under Windows 8.1 where the icons do not move with the fences. This problem seams to appear randomly. It may be related to playing a fullscreen game and then returning back to the desktop. When the fences leave the icons behind they are also not visible on the desktop. fences are acting like a portal to another world...through the looking glass indeed.
I think this is related to the desktop pages feature. Even though I have always had this feature disabled, when I have the problem I can click the Enabled checmark and then click it again to disable it and fences start behaving correctly again.
I am using 3 monitors on an nvidia card with a 4th on a second video card.
Windows 8.1 with 8G of ram, quad core intel sandy bridge
screen rez is 2560x1600 with two 1600x1200 monitors on each side turned 90 degrees (commonly called a PLP setup)
4th monitor is a small display in normal Landscape video mode on a second vid card. no fences located on it.
Fences release 2.12
