Can't see Mini-Registration on Frosty Theme?

I'm trying to get the quick registration form show up alongside the login box. I use the Frosty theme so I'm going to:

THEMES > FROSTY > DASHBOARD > DISPLAY MINI REG set to YES

But I'm not seeing it (URL provided in site details) and just getting the register button.

Is this a bug or am I looking in the wrong place to activate this?
