Hmmm... I have to say I never saw the serial number thing, and there have been a few times when I've had Poser and Vue opened at the same time, while doing experiments, and Vue hasn't whined about anything. you know, it makes me wonder though, particularly the serial number thing. Why would it be concerned about a serial number, unless it had been "told" to look for one? or is it just a really weird error? How does Vue even know Poser uses serial numbers, unless it was told?
