Hi Judy
In addition to what Larry said, I'll offer up the following.
I've got an E-Mail message from a student that attended a Captivate
class I recently conducted. She is reporting the same behavior as
you are seeing. Part of her message indicates she is seeing
multiple instances of the same Audio file name (but containing
different audio clips) in her project. So I'm guessing that if this
is truly the case, Captivate is becoming confused about which
"Recording 36" should be played when two or more exist.
I have no idea how this can even occur, but am suggesting
that she attempt to rename the different clips so each is unique.
I'm hopeful this will resolve the issue.
Might be something to check. Look inside your Library panel
to see if you have multiple files using the same name. If you see
such behavior, I might suggest attempting to rename so you don't
see duplicates.
Cheers... Rick
