For my main project I'm using a lot of contextual musics. Basically when you solve a riddle or simply examine something important, a music is played (through the "play sound" action part).
Problem is, most of the time the player can change scene while a sound is playing. I don't know why, but the last version of Visionaire kills every sound that's playing, apart from the background music. In VS 5.06 I solved this problem using an "immediate change to scene" action part, but it doesn't work anymore!
