Iframe question

[vcllvc]

I set up an iframe which point to yahoo.com in my page, and when I click on the links within the iframe, it take over my whole broswer.
Is it how it should be or I did something wrong?

Thanks in advance.

Yahoo uses this line in the main page at the site:

<base href="

http://www.yahoo.com/"

target=_top>
