Installed Scrivener NaNo 2 on newish iMac running Snow Leopard: fast install, looks good!
Tiny flaw:
Scrivener > Preferences > Corkboard > Position Pins:
The two radio buttons (Center and Right) are greyed out with the “Center” button showing a (greyed-out) yes. Not possible to activate radio buttons.
best wishes
