DraftSight on second monitor oddness

I have a laptop that has two additional monitors connected via DisplayLink.

If I run DraftSight on the main laptop monitor, then everything works fine. (Pretty much, although I have to say that the 2020 SP1 release is horribly buggy.)

However, if I move the DraftSight window to one of the other monitor screens, then lots of things stop working.

For example, the GETXY command prints coordinates to the command window when on the main screen, but does nothing when DraftSight is displayed on one of the other screens.

There are tons of other oddities, too.

Anyone know why this is happening? Is it a bug?
