Hi, i am a Mac OS X user and have installed Microsoft Office 2008 for Mac on the same. Related to my office, i have made a PowerPoint presentation with sounds and some movies as well. Every things is good, but in the meanwhile of the presentation, the sound stops itself. What i need is to make the sound play continuously during the entire presentation in PowerPoint 2008 for Mac. Do you guys have any idea how to do that? Please let me know. I appreciate all your help..
