Yes, it is an AC problem and GA support have basically been directed to to send us on a random wild goose chase rather than fixing their code. My expert says it's a code problem, and basic practice is all unhandled exceptions need to be handled. It's an error going up the stack and blowing it up eventually. He says the .net framework version is also about 7 generations old. I think the current company isn't really caring about us anymore. With my PA, I'm paying 3000 dollars per year for GA. The only choice seems to be change EMR. In the meantime, we should ALL call support on this.
