I am having the same problem! I am on the Adventure Through Inner Space Quest (Easy), and I earned the "Autopia Race Blue" Magic ... and when I click it, a car appears, but it does not go on the race track to let me click on any of the gas cans. My car vanishes in a few seconds. Then I have to wait a while before I can try again, and still nothing happens. Is there a glitch? Or am I missing a step? I'm new to the game. I'm just trying to enjoy it, but I'm stuck on this quest. But finding no solutions.
