Is there a way to stop the audio (music) in a tour? I've seen other programs where a button was available to push to mute the music?
While your project is open, click on Skin and under the tour buttons (you sometimes have to click on "Tour Button in the lower left corner), there you will find the mute button. Select the mute button and to the right, you can insert your own image. There are some images provided by TW in the images folder provided with the software.
