it's a windows bug...when it happens, click on taskbar with mouse, then click on npvr...fixed..
when it happens for me, npvr still has focus actually, just the taskbar shows..
sometimes happens with taskmanager too..
I noticed in Windows 10 that when I set a task to trigger the start of NPVR upon bootup, the task bar is always present, thus requiring a refocusing with a pointing device. The remote will not work with NPVR until NPVR is focused and the task bar minimized. This happens every time. This does not happen in Windows 7.
So it seems that in Windows 10, starting in 'full screen" mode is not quite full screen.
Is there a way to start NPVR upon PC bootup without creating a task to do it?
