We have now completely eliminated the Catalyst system as the cause of this problem!

Sorry, it was just a series of unfortunate coincidences where every thing we did to reduce the load on the Catalyst systems seemed to directly correlate to an improvement in the time between glitch incidents and the fact that this is a show with very little heavy mains equipment or motors in a modern purpose built venue with no history of power supply or RF problems

We are now trying to work out whether the projectors or the Smart E Cat5 convertors are the problem, and the source of the interference.

Thanks for reponding so quickly and firmly but politely pointing us away from the Catalysts being the likely source of the problem.
