Very annoying bug.
Playing in windowed mode, Windows 8.1

It can take anything from a couple of turns to far more, keyboard strikes no longer work. Mouse works only to access main menus and not unit menus or unit movements.
I have to quit the game, re start it and load to be able to continue properly.

was it solved?

As far as I know, no.
I gave up on the game.

it could do with drivers and windows. tested on another Windows?

The only other Windows version I have installed on my computers is Windows XP. I haven't tried it on that machine as it is severely underpowered for modern games and Windows XP is not supported by this game.

what gfx drivers u have?
I had lot of different issues with win 8,1 as it is in my opinioon worst windows version.

Try win 7 or win10 upgrade?

Hello trusteft,
we are sorry to hear that you have these issues. It is the first time such a bug has been reported. Would you mind to change the graphic settings of fullscreen (if you have it turned on, please turn it off and vice versa).
Let us know if that changed it and the bug does not occur anymore.
Thank you
