Is there a way to minimize the game window while I am playing so I can look stuff up without saving and quitting the game? (Don't know if it matters but I'm running Mac osx)

I can do it by pressing the Windows button (or the one next to it, I'm not sure). But on a Mac, I assume you don't have that.

In windows it can be done by alt-tabbing out of the game, I think anything similiar should work on MacOSX.

Don't know though, don't own a Mac.

Alt-tabbing in NWN doesn't work. Not for me in any event. It never has for some reason.
