Feedback Layer - sound of another layer playing
I'm stuck with a problem I really don't understand.
I have a question with 2 layers : Correct/Incorrect.
Each layer has a sound effect (Correct/Incorrect) defined in the FeedbackMaster.
If the answer is incorrect, the learner can click on "Correction". When clicked, this button opens a lightbox with the correct information.
Here is the problem: When you close the lightbox, the "correct" sound effect automatically plays. I don't know why, I don't know how to fix it. It only happens the first time you Lightbox the correction slide. If you click a second time, the sounds doesn't play.
The file is attached. If someone can help, I would be very grateful. I lost many hours trying to fix it. I assumed my file was corrupted but I tried with a new project and it's the same behaviour.
Have a nive day,
