Hi, I am running an mp3 sound file as a backsound to a power point show. This worked fine on windows 7 (but I had other freezing issues also described on the forum) so switched to my lab computer running Vista. Now the sound will not play in unison with the pps - only after I escape from the slideshow. I have tried modifying the backsound as a que file and as an exp file and no luck. Suggestions!!???
Thanks
