Start 1.9b3 where there are no saved games.
Click on "Load Game".
The 'No save files...' window will appear.
Click "OK" to return to the game start screen.
If the mouse is not moved then clicking on "New Game" (which is in the same place as the "OK" icon was) will show the 'No save files' window again. This can be repeated endlessly.
It requires moving the mouse slightly to reset the 'bias' to the "New Game" icon to start a game. This can be seen as a sunrise appearing above the half-earth image.

Possibly the game should check which icon the mouse is over as it changes screens, rather than requiring a movement to reset the icon.
