How do I prevent High Sierra from closing windows when sleeping?

Whenever I leave my computer running for more than an hour without use, I log back in and all my windows/apps are closed. This never happened with El Capitan, and now happens all the time with High Sierra using the same Energy Saver and Screen Saver settings (Computer Sleep set to 3hrs, Display Sleep set to 1 hour) but it still occurs even when I select "Never" and uncheck "Put Hard disks to sleep when possible."

I usually work on complex projects with numerous windows open and often step away for an hour or more, so it's very frustrating to re-set my workspace every time I return to my computer.

iMac, macOS High Sierra (10.13.3)

Ok go to the Apple at the top left and click, from the drop down and select Log Out, now in the dialogue box that pops up make sure the box is checked Reopen windows when logging back in. Without this checked you lose your windows.

Sleep mode does not cause logout or apps to close.

If you need to log in, then you were logged out. Something other than system sleep caused that to occur. Read Set your Mac to log out when not in use - Apple Support.

Ok, I'll try unchecking "require password after sleep or screen saver begins" and see what happens. I had this checked when I had El Capitan and always had my windows open back up upon login, but mabe this is differenc with High Sierra. I'll see!
