Dual Monitors - OS 10.11.5 & WIN 10 = Blue Screen of Death
I use Multi Monitor Wallpaper App to select image across 2 monitors. Sometimes one (or both) monitors revert to El Capitan background for unknown (to me) reason. The current image slides off screen to reveal El Capitan background.
Now right screen is 'Blue Screen of Death' (Actually the WIN 10 aqua screen) - seems from WIN 10, unable to return to Multi Monitor Wallpaper on right screen, shut down WIN 10 (via Parallels 11) - still unable to get rid of 'Blue Screen of Death' even with “Restart’ or Shutdown and Start as I have done in past.
Read something about WIN 10 'Ease pf Access' but no help here.
How do I prevent this problem or at least return to Multi Monitor Wallpaper images without reboot.
