Found a workaround. I have a utility called "Borderless Gaming" I bought on Steam many years ago that forces windowed games to borderless full screen. You can also toggle a hotkey that locks the mouse cursor to the borderless full screen. This utility works perfectly on JA3 even though its 'full screen" is already a borderless fullscreen.

I second this request. Can't edge scroll when your mouse just goes to the other monitor. Annoying.
