I have a window that opens with the home page (confirmation window), when I set the close options as in the image below, the window won't close when the check box is clicked (as I expected). Either I have to select "click outside to close" or choose another style option. I did not want to have 2 clicks to get rid of the window.
Is this how it's supposed to work?
Ya, the checkbox confirmation and not having a button don't really go together.
Generally speaking, the two separate clicks is the norm as it [theoretically] discourages misclicks and ensure people acknowledge something.
That said, end users gonna end user, and ignoring content is the norm. I would go with a custom popup and replace the checkbox/button with a custom button. E.g.,
Using the Don't Show This Again Option. The Window will close by clicking outside or Ok. They will only need two clicks to make the Window not show up next time.
