I had to switch to "classic" style because all the **** ads and trash you pile into the mail page bloats the ****** till it can't fit through a hanger. And then the mail randomly switches itself back to "new" style for a couple days before going back to what I actually set it to. The same with everything else owned by yahoo, it gets bloated, useless **** crammed in that no one ever uses and causes everything to fall apart, but instead of fixing the initial problem and getting rid of the bloat, you add more to it while taking away the things that actually worked.
