--- Comment #23 from Ilya Chernykh neptunia@mail.ru 2009-01-05 21:41:34 --- Well I can say that the cursor appears entirely without artifacts if starting the game by double-clicking, but if to start the game from command prompt regardless of options I see the black square around cursor.
This is disappointing since the only way to start gthe game with resolution higher than 1024x768 is to run it from command prompt with corresponding options.
