Is it safe to stay logged into ipassword (by changing to 8 hours) or is this a security issue?

@GreyMIP your comment "it doesn't sound super-likely that someone would stumble across 1Password on your computer while it's unlocked". interests me. Are you saying that if a computer using 1P is unlocked and 1P is unlocked it is possible to uncover the 1P password? Or are you merely stating the an unlocked computer with unlocked 1P leaves someone's Vault open to searching? If it is the first, I'm concerned because I did not believe that was possible. If it is the latter, that is obviously true and doesn't worry me.
