Yah I've noticed that too but it's hard to tell when the score board will pop up. It's more ninja than the horses (though I don't really understand what people mean when they say they can't hear horses, I just like the idea of a ninja horse).
I'd like it to be like in CS where it pops up, you go 'damn I'm a sexy beast' and then hit tab and it goes away so you can talk/gloat/say gg/take pretty screenshots/etc.
