Thank you, Jim for answering my cry for help. I am using
PowerPoint 2003 and Adobe Presenter 6.0.
I think I have isolated my problem to my PC. I have found a
workaround for the time being. If I transfer the audio files to my
thumb drive and them import them into the presenation, I have
success.
However, when I importing them from My Documents, I get a lot
of strange files in the Data folder.
