Peculiar Present Problem

Hi, Folks!

I just submitted a support case and the e-mail I was sent suggested I ask for help here, too -- so let's see if the community can crack this faster than Articulate Support!

I've produced five other E-Learning modules (they're basically mini-lectures) with this same version of Presenter '09 and PowerPoint 2010 (32 bit), and this is the first time I've run into this particular problem.

No issues with the project until the publishing stage. Once I publish, something very strange happens:

The audio for slide 6 starts playing whenever I go to slide 4, 5, or 6. This means that on slides 4 and 5, we hear the narration for slide 6 on top of the narration for slide 4 or 5. This happens whether I jump to the slide, or let the module progress there naturally. Pressing the pause button does not stop the audio for slide 6, though it will stop the audio for slides 4 or 5 if I'm viewing them. Seeking within the slide has a similar effect -- I can seek through the audio of any other slide, but the only control I have over the audio for slide 6 is the volume control. If I preview slides 4 or 5, they have not issues at all. But if I preview slide 6, I once again have no control over the audio.

There's nothing fancy about these modules -- no embedded flash movies, engage interactions, or annotations. (They're basically just mini-lectures.) I've re-published the project twice, tried different web browsers and operating systems, and I still get the same result. I need to finish this project no later than the end of this week, so I could use any help you can provide.

Many Thanks,
Andrew
