@Seth: I will monitor next time it happens to see if I can ALT+TAB as well, thanks.

Key presses are not registered by the field and it looks like it is frozen (except by the cursor blinking). What I had to do when this happened was to wait until the tentative expires (screen goes blank) and then try again - then it worked. However the application running in the foregroung (or background, if you consider the lockscreen is on top) received the key presses, i.e, my whole password - you can imagine the implications if it was a chat window. I'm using 14.04, upgraded by 04/17 from 12.04 - all packages updated.
