blutok: I can't exit BG:EE, I'm going to menu, choosing exit and exit to windows but i takes time, loading and loading... I click several times and there coming pop-up window which says: "Program not responding/working (dunno how it is in English, I've got Polish OS and the game), do you want to close it or wait until it will respond?" I click close and voila, the game is closed. You should do something about this, I'm worried one day my saves will be gone.

Sarafan: Try Alt+F4. Don't worry, it won't do anything with existing saves. Just try not to shut down the game while save is in progress. I don't know if you're using Galaxy, but BG EE supports cloud saves. You can always treat these as a backup in case anything happens with the saves on your computer.

blutok: Yeah I know about alt+f4 but this is not the point and not the way it should have been working.

Engerek01: Are you using Galaxy, GOG's client for games?
What is your operating system?
Have you done an uninstall/reinstall?

Engerek01: Try running the game directly from its installation folder, without Galaxy. Play a little and see if you are experiencing any of the problems you have with Galaxy.

Try disabling your anti-virus program.
Try disabling cloud-saves.

I believe we will have a better understanding of your situation if you try these individually.
