If you are in full screen, and you go to Video - Pan&Scan - Auto option, it works perfect. But if you are watching a panoramic movie (with black borders), and you use the key acelerator ('O' key, by default), the image zoomed, but the black borders still remains!!
Another "cosmetic" bug. At Options - Preferences - Key definitions, the name of the funtions for the keys are in english, even if you use a lang file for another language.
