You know, this being 2004 and all, you'd think that you'd be able to embed an MP3 or WMA file into a PowerPoint presentation instead of linking it.
Think again. PowerPoint only allows you to embed WAV files. Was pounding my head against the wall for a while on this one until I read the fine print on the Microsoft web site.
Why not just link the file you ask? Well this presentation will be emailed so linking isn't an option.
Besides WMA and MP3 have been around a while, so why doesn't PowerPoint support them fully?
