Under A Killing Moon Black Screen on exit

After not having played UAKM for some years, and probably on an older computer, I decided to install the GOG version yesterday.

The game works perfectly, but when exiting the game, all I get is a black screen and I have to reboot the computer to get back to the normal desktop.

Has any one out there any idea how I can get rid of the black screen on exit as I don't want to reboot the computer every time I do.

I'm playing on Windows 7 64 bit, Graphics Card Nvidia GE Force 1050

Later today: The problem has fixed itself, maybe because I updated the Graphics card, or maybe not.

Anyway, the desktop now displays normally after exiting the game.
glad you sorted it out.
