Locking the screen

[Dennis J. Tuchler]

I've been looking for a way to lock my screen subject to my user's 
password, so that I could leave the screen with the applications and 
documents open while I left the office for a bit.  Is there such a way?  
When I check "save sessions for future logins" and then log out, when I 
log back in I find all the applications have been exited.
