I’m on Windows 8.1, NoMachine 4.2.27, when process “NoMachine Display Monitor” is running, I have what appears to be invisible 1px border around entire screen which is causing even full screen applications to lose focus when clicked on. I also have autohiding elements (IM client, Dock) which should appear when mouse hangs around edge of the screen. They won’t appear. Also if I move cursor to the screen edge and right click on desktop, no context menu is shown. If i move just 2px away from the edge it works. After I kill this particular process, everything works as it should. Anyone else experiencing this? Caused me quite a headache :-/
