iframe breaker breaker? I need to break the iframe breaker

I'm loading a page in an iframe. it's someone else's site, and it's all legit. but in that frame, they've got some JavaScript that redirects the page... and it's obviously using "top.window.location=..."; it takes over the entire page. it's breaking out of my iframe! I really want that stuff to stay in its iframe where I put it. I think breaking out and hijacking my page is actually pretty rude. Is there a way to stymie their framebreaker? perhaps when they call "[login to view URL]", it loads inside my iframe? Can I define that iframe as the "top"? ha ha I'd really like to stay with the iframe, not open a popup window, for reasons too banal to explain
