Touch/Scroll fails when connected to multiple monitors

[jpc1963]

I use the following to scroll through a list:
RemoteTouchScreen.Scroll(FindElementByAccessibilityId("myID").Coordinates, 0, -200);

This works when no other monitors are connected to my laptop. When I connect other monitors I get the error message:
System.InvalidOperationException : An unknown error occurred in the remote end while processing the command.

Slightly more info. from visual studio:

WinAppTouchScreen.Scroll(UWPGetElement(automationID).Coordinates, 0, 200)' threw an exception of type 'System.InvalidOperationException'

Yes I think so.
I just have everything open in the main monitor now and ignore scroll errors as much as possible.
