Error: "Your Mac hasn't logged out because '1Password' failed to quit."

1P_Dave my "-" was because I wanted to delete the comment, but could not see how to :)

I was going to say that the workaround does not really help, as the issue is only an issue when I leave my MacBook unattended. If I logout or shutdown by hand I have no issue. I guess if you mean the workaround is to quit 1Password every-time I leave my MacBook unattended, then yes I guess that would work, but sadly I will forget!
