When I've used $ky, I've found that if you press back to get rid of the red dot, it appears again after adverts etc. Yes, it's annoying, but it's just one of those things we'll all have to get used to.
Also, the red dot is used very, very little at the mo. Give it a few months, until broadcasters and advertisers realise that it now works on ntl:, and you'll have prompts for it all over the place! Imagine how many complaints will be on the board then!!!!
