internet explorer

i used it to go on a chat site but then i installed yahoo messenger and yahoo is the new home page and now it says the site is a pop up how do i stop it from blockin it

the page that is blocked is the page used to chat so u need it

What pop-up blocker are you using with IE? Is it Windows XP Service Pack 2? Google Toolbar? etc...

Whatever it is, try to look for the pop-up blocker button and look if there's an option that says something like "Allow pop-ups on this site".
