At the end of every turn it takes the AI approx. 15 sec to process the other civs, but then when the "waiting for other civilizations" message disappears and my turn starts again with e.g. the next build orders for a certain city or a pop-up with a leaderhead etc. the program freezes up for about 75 seconds! every turn again and again.
