After hitting Enter after typing the save name, the screen goes black and nothing happens. I waited several minutes, but nothing. Still, I can hit F12 and load an *.sgf save, so maybe the game didn't crashed (?).
What I don't get, where the game would make the in-game saves? Ishar saves always in the game folder among the game files - but if the "folder" is a packed exe, how could it do that?
You must wait ~15s-30s for first save
