Hello. Just got new computer with Vista Home Premium. Have set parental controls to medium for my son. I am the administrator. If I go on "You Tube" I can see the videos and hear the music = it all works fine. However, if my son goes on you Tube he cannot see the videos/hear the music even though I have put "You Tube" in as an allowed website in Parental Controls. All he gets is the little circle (or timer) as though it is looking for the relevant video but, even if we wait ages, the video never appears. I have tried unchecking the "enable hardware acceleration" as per another post on this site but that made no difference. I'd be grateful for any suggestions. Many thanks
