Please realize that even though the software is made by Microsoft, it's
running on a processor that is absolutely NOT designed for Windows. What
VPC is designed to do is translate the thousands of transactions that a Mac
processor does per clock cycle into the hundred or so a PC does. No matter
what you do, VPC isn't going to run like a physical XP machine. Look at it
this way: VMWare, which is designed to run any x86 based OS on the market
on an x86 based server, works wonderfully. How many emulators that work and
work just like a real Mac, are on the market for x86 machines...??

Sorry if this dashes your dreams. I am a Microsoft Windows-based network
architect. Trust me, I would love to see this more than anyone ;)
