In my quiz game I flash a cue when a person touches a wrong answer, and present a success messages when the person touches the right answer. Both right and wrong answers are displayed at the same time. The flash behavior is about a second long.
Interestingly, when i press the wrong answer and then immediately the right answer, even when setting the cue text to invisible, once the cue text flashes, ti does not become invisible until the flash behavior completed. To ensure that the invisible action indeed makes the flashing cue disappear, i must first submit a stop flash action.
While this is a minor issue, I thought to report it nevertheless since its somewhat counter-intuitive.
