I've just upgraded to V4 and installed it on a Mac Mini (intel core 2 - 2Ghz - 2 GB RAM - 320 GB HD). During programing and playback, the video output freezes. No control from console. If a movie is playing and you lower the memory fader of this movie, it continues to play. No fade out. If you try to access a layer - nothing happens. But I can toggle from full screen to control screen. I'm using a CIB as interface. The console is an Avolites Pearl 2008. Anyone has an idea on what might be causing this malfunction?

Thanks,

Samuel
