Deskscapes Problems with WIN 10 November Update

I recently uninstalled earlier version of Deskscapes 8 and installed the latest 8.5 version.  I had been waiting for a version which would work with windows 10.  When I select a background and select it to display on monitor 2, my background switches to a black screen on both monitors.  If I select for Monitor 1, it will display correctly.  Only way i can get two different backgrounds is to first display to all monitors, then select different background with monitor 1.  If I select for monitor 2 first, background goes to all black on both monitors
