Thanks for replying. I have launched the Slingplayer on my laptop and it is running as I type with the remote visible.
Is that what you meant? If I press Ctrl and Alt nothing happens - but maybe I am not at the right place? I have also found another suggestion on the Slingplayer help section which suggested that I need to reconfigure my Slingplayer (at home in London) as it is confused about which network it is running. Obviously I can't do this myself as I am in Geneva but I might try and get my son to have a go. Does that sound logical to you?
