After pausing for several seconds, and resuming playback, the OSD stays on the screen despite pressing 'Back' or any other remote press. It's like the OSD hangs and stays on screen, no matter what I press, even though playback continues. The only key it responds to is the Home, w/c takes me back to the Home screen, so I have to restart the video. Anyone know how to fix this? U1 in latest FW12.
