Identity safe login issue

I have identity safe set to log out if the computer is idle for 15 min...and when it does it prompts me to retype my password.  Perfect.  My problem is with that setting only, if I manually log out and close the browser, when I open the browser again I cannot enter my password nor can I access my settings.  It shows "log out of identity safe" but when I click it nothing happens.  The only way I can log back in is to restart my computer, or log off of windows and log back in.  I am using firefox 3.0.5 with aero fox theme. 

 

It would be really nice if there were a setting allowing identity safe to log out automaticly whenever the browser is closed as I forgot once and it actually displayed one of my passwords when my friend was on my computer.   I then had to go in to that site and change my password.
