Does not lock after I log off computer

I have a passport permenately plugged into a computer I share with other users. In the old version of Smartware, it would lock if I logged off. Now another user logs in and the drive is unlocked. The only way to lock the drive now is to remove it and plug it back in. Am I missing a setting here? I want it to lock if I log off the computer as a user…

Thank you…
