Is there a way to play a music with a .wma extension in
PowerPoint slideshow mode? I've inserted a .wma file as
an object but can't figure out how to launch it when the
screen is accessed. Also can I control how long that file
plays, such as getting it to stop after a specific screen
is displayed, or after a certain amount of time, much the
same way one can control a .wav file that is playing
within PowerPoint?
