Can the email format be changed to the way it was before?

I had to set my Yahoo! mail account to the old-school view because it doesn't work on any browser except Explorer. I don't use Explorer at home (I own a Mac). I think all I had to do was click on the link at the top that said "Original Yahoo!Mail" or something along those lines. But this was months ago. They may have taken that away to get people to stay on the new layout.
