Argh! I am currently on hold on a software tech support hotline. Unfortunately I am finding out that they know even less about their software than I do. They are finally willing to concede that the software cannot do what I need it to do, but are still adamant that there is a way around the problem by manipulating inputs to simulate a similar condition. They are wrong. I'm determined to get an outright confession that their software is useless. I may be waiting a little while...
