Not locking 1Password8 on browser close

Sorry but it has been a long week here.

The reason why I wrote this was as I had explained I believed that 1Password never locked itself when only using the extension and not having the app loaded. Before I wrote the initial post in this thread I closed the browser and then started it back up. 1Password extension remained unlocked so I posted here.

I just now closed the browser and opened it back up and this time the 1Password extension was locked and I had to enter the password. This is what I always would want to happen. I do not know if the experience earlier today was a blip or what but I will have to keep an eye on 1Password and see whether it behaves itself.

All of the above was without 1Password app running.

P.S. What does 1Password mean "when the computer locks"? This computer does not hibernate nor sleep. Nor does the Windows lock screen come on when the monitor blanks out due to inactivity. In this case, does the computer actually lock?
