Why am i prompted to login when i use hyperlinks at websites where i am trying to "contact"/email that website

I've had this trouble before w/an MSN account, but never w/yahoo...and it seems to be a fairly recent issue. i am on a website, say for a a band, and i want to email them, so i hit their "contact us" link and instead of an email window popping up, like i'm used to, i am prompted to RE-login to yahoo. what happened to change my email settings? and how do i fix it? i'm no computer wiz, so i need simple, clear instructions. thanks!
