I've chosen the Identity Safe (NIS 2011) option to "Automatically log out of Identity Safe if computer is inactive for 15 minutes". The 15 minutes appears to be defined as 15 minutes of elapsed time while the computer is running. So if I suspend the computer, and then restart it the next day, it will still be logged into Identity Safe. This undermines some of the protection the "Automatically log out" option is supposed to offer. I believe the 15 minutes should be defined by the amount of time that has passed per the system clock.
