The hugely irritating adverts on the "improved" home page have prompted me to complain three times to BT Yahoo. Their response was that we get the home page free of charge cos it's paid for by the adverts. I've had the old home page, advert free, for 4 years so why the change to adverts now? The more people that make a formal complaint the better. I have told BT that I now have a completely different home page and that I am shortly going to change my ISP. Suggest you and others do the same.
You might try making your home page back to the old one = http :// homedotbtdotyahoodotcom (without the spaces). You automatically get transferred to the new home page, but in my case the adverts freeze and don't pop up. I suspect this may only be temporary, but in my case it is working at the moment. I use Firefox as my brower.
Anybody else out there with other suggestions as to how to get rid of the adverts - much appreciated.
