Replay button not replaying a layer with audio
I have a problem with my project in that a replay button which was working but then it didn't. During the build, I was testing each slide in the preview as I went along and until I reached about the 10th scene in the build when the problem with the replay button occurred. Since then, I have removed all buttons from the main project and remade the replay button only for it not to work any where in the project.
The project has 16 scenes and each scene has between 2 - 7 slides/screens. Each scene contains at least one slide with audio, some have up to 3 slides with audio. The total size of the project is 36 Mb and built using SL360.
Attached, is a very cut down (two scenes) version of my project at 4 Mb, for demo purposes only, featuring only one scene of a particular subject and this version was an earlier incarnation of the project (design-build) so not influenced by any bugs, or is it?
For those that download my demo out of curiosity or to help, thanks, the problem slides are 2.2 and 2.3. I am thankful in advance for help or advice offered but I'm off to lunch now (UK time), so speak soon!
