Making the window fit the image in PS 2024

Hi all.

So, I'm in the habit of having it set up so that zoom does not change the window size. That way I can. have two (or more) images side by side & can zoom in & out on different parts of each image to compare.

In the past, when I did need to change the window size, I've been able to zoom out on the image & then click the green traffic light to have the window change & fit the image.

Is that no longer possible? What seems to happen now is that the green button causes the window to go full screen, which is entirely redundant as that's what the "f" key does.

Is there an option anywhere to revert the behaviour back to what it was before?
