I am posting this to see if anyone else has come across this particular lock up in the new version. The game 'turn' button disppears away. You can not select a new ship or planet or starbase but can use all the 'management' screens of technology, progress etc. If I do a quicksave and then reload, the turn button appears and I can proceed for three to four more turns before the same thing happens again.

I'm wondering if anyone else has come across this. I don't want to lose this game as I'm having a lot of fun playing as the Krynn with a horribly underpowered military but unbelievable cultural missionaries. (and yes, I've sent in the requisite debugg and zipped saved game to Stardock).
