Hi, New member here, but PTE user since version 4. I just downloaded the latest version (6.03) and I'm having trouble with syncing a single mp3 (3:10 long) and 46 photos. I'm using windows XP with everything updated; I have the photos and mp3 in the timeline; I have "Auto spread slides along music" and "Synchronize music and slides" checked, but the slides remain at the 4 sec. default. What am I missing? Thanks.
