Okay, every time I open up Tremulous, I now see an "options"...option along with the default Play, Mods, etc.
It was never there before, and it DOES let me configure the graphics, but when I am in game and I try to change the controls and I click on "options," nothing happens. The little noise sounds when I click, but nothing comes up.
And just to clarify, I AM playing Tremulous on a mac.
