I run windows 7 and I am unable to set yahoo as my homepage; when I try to do so, I get the message "this address is not valid" but, after rechecking, it is the correct one I am using. I have attempted to do it, via control panel, and also from the yahoo mail homepage, with no success. I am also being advised to go into my yahoo browser settings menu, but cannot find the button which allows me to do this. Any tips would be helpful. Thanks.

what browser are you using. as in Internet Explorer, Firefox, Chrome?

You can only set a home page in a browser.
Such as Firefox, Safari, Opera, Chrome or Internet Explorer etc
Yahoo does not have a browser
its main functions are search engine or email provider

What is the URL of the page you are trying to set as your home page?
The BT homepage, which used to be BT Yahoo! is now http://home.bt.com/

Which browser are you using? Instructions here for various browsers

Internet Explorer.

Managed to get it sorted. Must just have been playing up.
