I downloaded version 5.2.2, and I had accidentally clicked on 'Deattach' which was on my 2nd monitor, but after clicking it, I can no longer reattach it. My computer and LittleBigMouse are recognizing the monitor still as present but Windows (in the display settings) simply states my 2nd monitor 'isn't active' and gives only grey boxes when attempting to change it.
I apologize, I resolved it. Windows changed the setting under 'Multiple displays', (in of course the 'Display' tab) from 'Extend these displays' to 'Show only on 1', simply revert this decision.
