Game setup & tech trading

[Barnacle Bill]

Is there any way to check the game setup options on a game in progress?

I usually play with the no tech trading option. I do this because the AI are tech trading whores and left to their own devices everybody has all the same techs except racial ones.

I also usually don't agree to treaties involving tech exchange (which would supposedly not be allowed anyway, under my typical game setup). I can't remember ever seeing an AI treaty offer that didn't include tech exchange, but I counter-offer and deselect that.

This time, though, I accepted one such a treaty as offered, and now every turn my new AI ally gives me a dozen techs or so - and it has been going on like that a very very long time. The rate of progress is such that I'm sure he's getting stuff from several other AI races (that or he has a billion research points).

So, either I forgot to de-sellect tech trading in the game setup (which is what I want to check, hence my original question), or there is a bug whereby they trade anyway regardless of the game setup option.
