I have created a show set to a single piece of music. It is important in the show that the slides are coordinated to music cues and I spent some time getting this right. However, I find, when running the show that the speed with which the PC handles the pictures and transitions varies and the show gets out of sync. It is not the same every time. Have tried running it on several PCs but the variation seems quite random. I think this is because apart from deciding when the music starts, there is no connection between the music and pictures. Has anyone come across the same problem and managed to solve the issue. TIA, Nigels. P.S. Using P2XE v4.31.
