Indy, thanks so much for the information. If the issue really is that there is just a ton of stuff going back and forth, then the suggestions given make sense. I had been assuming that AC's design was more what I was accustomed to, in which case network speed would not really enter in greatly, and I just could not understand why it kept coming back to that. Knowing what you have said, then the issue makes more sense, and putting in the effort that you, Bert and others have suggested is clearly worthwhile.
