Steps to reproduce:
1. Load game.
2. Press any key to bring up the main menu.
3. Move the mouse anywhere out of the menu entries.
4. Press Down arrow.
Expected result: the menu cursor sound is played, the first menu element is selected.
Actual result: the menu cursor sound is played, no menu element is selected.
Repeated Down arrow pressing doesn't give any result, either.
If on step 4 Up arrow is pressed, the last element in the menu is selected.
