Just to follow up I contacted the original poster from the other list requesting that he clarify and he sent the following. "Dear MBurke: I asked the guy to write up what you requested about using the Mac and a PC at the same time. I'll see if he'll do it. He is an instructor in computer science at a university here and doesn't really think it is that big a deal. Easy for him to say. We'll see what happens. I really don't know what he could say that would satisfy everyone without their actually seeing it in action. Alexander" If I get the write up I will forward it to the list. MBurke
