It seems rules/instruction cards are not displaying correctly (for me) when in-game.
I can bring them up normally in the PinballX menu, but if I want to view them while playing a game - by going to the exit menu and selecting "Intructions" - nothing is displayed.
I do hear the sound that normally plays when displaying the instruction card, though. So maybe they're actually displayed behind the backglass or something...
I'm using swf instruction cards.
