This may be a bug just on my setup as I've seen no one else report it on V28. If I press F7 or the praying hands to get info on Religion, all I see is a picture of plans for pyramid design. Nothing else until I hit "cancel" at which time two windows with no information appear and then I can do nothing. I have to hit some other "F" key to get another screen and then exit.
I'm deep (several hundred turns) into a game where I've never been able to assign a State Religion. I have been the only character on my "continent" for centuries, have one religion (until recently) but can't make it or the one recently found my religion as the screen does nothing. I'm reasonably confident that if this were happening to others I would a have seen complaints.
As a religious aside, not bug related, how can one take advantage of a religion that you've traded for? It seems that although I presumably have received a new religion via trading, none of my cities actually has it and I can do nothing to create missionaries, monasteries, etc.? How is this properly handled?
If the answer to these questions is obvious, forgive me, as I have had two drinks called Winter Frisbies which are surprisingly tasty and delightfully powerful (if you're safely at home and going nowhere)
