Mouse coordinate with 2 monitors

Messing around with (System) nodes with more than one monitors connected…
Looks like some nodes realize the presence of more monitors, and some nodes not.
This is the simplest patch to see it:

if you have only one monitor this work well, or better: nothing happen when you click the middle BTM because it set the mouse with same coordinates.
When you have more monitors, clicking the central BTN let the mouse pointer “jump” somewhere else
