Mac mini output freezes

[samsc]

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

does sound like a dmx thing-
what happens when you program a very simple cue to just fade in and out a white square?
does this happen?

Mac Minis get hot. Don't ask me why but of 8 minis I have taken 3 back to Apple for locking up. Apple won't explain why but simply swaps the mini for me. I have gathered it's a heat problem from the Apple support articles and the console results.

this particular problem is not a lock up of software- or heat -
