How on earth do you exit Quick combat mode once it is activated? The manual just says that you interrupt it, but how do you do that? I have tried getting in other commands like move while in combat but that does not seem to do it.
So, turning off quick combat is actually one of the features of Gold Box Companion, among others. It's actually the reason I first downloaded it. http://personal.inet.fi/koti/jhirvonen/gbc
GBC does a lot of other stuff too, like allow full character editing. So if this is too tempting to you, maybe try another solution.
