Preview icon stays in dock after being closed

Thanks for your reply.

I'm not trying to put it in the trash.

My issue is that 'closing' the window doesn't seem to close it fully, it remains in the Dock. I don't want it to remain in the Dock, I want it to close fully.

Whether the white dot is there or not, it still stays there until I click the icon in the Dock and 'quit' it.

I want to set up my mac so that when I 'x' out of the image being previewed, the preview window fully closes, including the icon in the Dock.

Any other suggestions?

Thanks for your reply.

Yes that was the first thing I did.

I think I just figured it out. I have to close the preview window, and folder, and then click on the desktop somewhere and that closes the icon in the dock. Sometimes there is a delay in it closing, but it does seem to close. Also, clicking on anything else like opening other windows doesn't let it close, it just stays open.

So the solution seems to be

1. System Preferences>Dock & Menu Bar> 'Show recent applications in Dock'
2. Control click on the icon in the Dock. Select "Options". Make sure "Keep in Dock" is not checked
3. Shut the windows, then click somewhere random on the desktop and it should eventually close.

Kinda strange~

Thanks for the replies.
