Comment 10 for bug 1311316

I just noticed two things:
 - If focus is on a text file when Unity locks, when you type the password is been typed in the text file (even if it's not visible until you manage to unlock clicking on top menu and clicking again in the password area)

 - Sometimes, visualizing a fullscreen video, system lock but it keeps showing one of the frames of the video making dificult to unlock. The way I found to unlock is to press ctrl+alt+L to lock and type the password
