VTS, you sound like me a few years ago. I was an almost-exclusive Pronto/RC5000 programmer when I got tossed onto a job with 11 VIA panels without previous product experience. VIA Tools is a good program and easy to work with, but you can't treat it like a Pronto program. It's set up to do things in a certain order, and it's difficult to jump around inside of the program and do things like a lot of us do inside of ProntoEdit. It has its quirks, and the best way to learn it is to go to Lexington for a training class given by Elan themselves. Your employer should pony up for it, especially with the magnitude of the install you're about to undertake. Classes are held every month if I remember correctly, and they're 2-day deals...
