Norton Identity Safe loses logins?

Hello folks

 

It seems every time my laptop comes back from sleep Norton Identity Safe "forgets" its status until I reboot my machine. The icon in the browsers' toolbar shows "Vault open" but all my logins are gone. Even if I use "Close Vault" and then authenticate again it will still show an empty list.

 

Once I restart my PC then it shows the correct list of logins recorded in my account.

 

Note this is the standalone Norton Identity Safe 2012.6.3.28, not part of any other Norton bundle. I suspect this could be a service problem, but since we can't simply restart the service, a reboot is required.

 

Any ideas?
