Can't select Full Screen (Mac)

Hi there,

I’ve been playing Democracy 3 for a while now on my Mac but for some reason whenever I open it now the screen is minimised, cutting off the bottom quarter. I can’t change the borders to see the bottom part, and when I try to select full screen or control/command/F it won’t work (full screen under view at the top is greyed out). Is there any way to fix this so I can play the game again?
