After closing Preview app, it remains "on top" - why?
Hi.
This question may sound kinda weird, but there is a thing about MacOS I don't get.
The situation is this: I am browsing a folder with lots of photos. I open one of them and when I close it, to open another one, I MUST click on the Finder, because I use keyboard arrows to move from file to file and look at the small preview on the Finder before deciding if open or not a certain file.
This happens because the app Preview remains "on top" (don't know if it is correct to use this phrase) even though I have closed the picture previously.
Is there a way to bypass this issue?
Thank you!
