DJV Opens across all monitors unless -fullscreen option used

I have a Windows 10 system with 3 monitors.; 2 are 4K monitors, and one is a 1080p monitor. They are at different heights, so the coordinate systems for each monitor have different baselines.

If I start DJV from the command line without any options, or by double-clicking on a video, djv opens across all monitors, which is unhelpful.

Simply specifying the -full_screen_monitor option does not solve the problem, the -full_screen option must also be used.

Perhaps djv could remember its previous size and monitor? I set the options for that, to no effect:

BTW, notice in the above image all 3 monitors are shown as the first monitor, a Dell P2418HT (HDMI). The other monitors are different.

BTW, when DJV is displayed on monitor 1, then the menu selection Window / Fullscreen is used, DJV moves to screen 2 and displays in fullscreen there.
