Ralph,
This is a bit embarassing but I don't really know. It was an old file hanging around so I don't know the version it came from. I never used VPC 6 or 7. The last version I had was VPC5 and I gave up because performance was so slow. But, now I'm starting to think this file was something that came from where I work, which means it was Microsoft Virtual PC and not Connectix Vritual PC.
So, I'm afraid until someone else reports something we need to consider this case NOT closed and we need to consider my post a fluke. I apologize for getting anyone's hopes up.
Paul
