fullscreen goes to black in primary screen in max 9

Hi,
With Max 8 when you create a jit.world or jit.window and you send the window to another screen, and then you send fullscreen message, the window goes to fullscreen, and I can mantain the screen of my computer with the patch.
I've changed to Max 9 and when I did the same thing the screen with my patch goes to black.

I'm completly sure that it's a silly thing, but I don't find the solution.

I'm with macOS Monterrey 12.6

Thanks in advance!
