Hello,
Openarena 0.8.5 doesn't save preferences on my Mac (Osx Snow Leopard); every time I run the game it loads default settings (screen resolution, sound, input and so on).
But it saves correctly the multiplayer settings: player name, model ecc.
Moreover, Z and W keys are mapped uncorrectly (swapped): so the W key is read as Z and vice versa.
Of course my keyboard works well and the problem occours only in Openarena.
