I was going to acess the elder sign(save point) when the game crashed, leaving the screen bright white. I guess this happens due to the way the game engine was implemented: I suppose whenever someone acess the elder sign(or the eye), the game call a loading function twice. First time to load the list of savegames, so the player could choose what slot to save in, the second time to return back to the game.
If the first "load" crashes, the result probably is the white screen we both have seen. If the second "load" crashes, the result is a 'clean' crash, no side effects on the desktop.
