Google AdSense and URLs

I have found something interesting about Google AdSense. The news.html
page on my site (saved in main directory) has one of the Google AdSense
banners on it. If someone comes in from the main directory or from
something else like /forums, adverts are displayed, however If someone
visits the site by going to /news (which directly launches news page in
a frame) the Public service ads are displayed. Is this a bug, or just a
coincidence?

Theres different codes for framed and non-framed. If you have the non-framed
code on the page and its a frame Adsense cant read it.<!-- ~MESSAGE_AFTER~ -->
