Dear Jim, Are your image files all under 200kb ? Yes they are. most are under 100kb, and I still get that problem. Have you used mp3 rather than a wav sound file ? It is mp3, as that gives much better sound. Is your mp3 file relatively small (96-128kcps usually is OK) 128kps Maybe it is the CD drive. I would guess the exe file is loaded up slowly, and to be honest I haven't tried it without music. Probably because I would like to create AV's with music. I am sure there is an answer, and hopefully I will find it. Jim, thanks for your quick response. Richard Did you use Custom Synch for your music ? Some are, some aren't. it doesn't appear to make a difference.
