<p>Small addition; the 3520 button moved the top left of the Window
to the middle of the right screen, but the window as a whole was
not centered.</p>

<p>Hi Thiago,</p>
<p>I ran this on Windows. My monitor setup is:</p>
<p>Left: 3840x2160 (150%) -- top left coordinate (-2560, 0) (-2560
because of scaling)<br>
Middle: 3840x2160 (150%) -- this one has a top left coordinate
of (0, 0)<br>
Right: 1920x1200 (100%) -- this one has a top left coordinate of
(2560, 0)<br>
</p>
<p>When started, the program appeared perfectly centered on the
middle screen.</p>
<p>Your program showed buttons: 4480 and 3520</p>
<p>The 4480 button moved the Window far too the right, off screen
and I had to stop the program</p>
<p>The 3520 button moved the Window to the Right monitor, but it
was not centered nicely.</p>
<p>I added a `peek(System.out::println)` on the screens stream.
These are my screens:</p>

<div>Could anyone with a multi-screen setup on Mac and/or

<div>On Ubuntu 24.04 the first button moves the Stage to the
end of the first screen (bit weird). </div>
<div>The second work as expected, it gets moved to the start
of the center of the last screen.</div>
