Thanks for the suggestion John.
However, I am using Shared Networking when the lockup occurs.
I just tried switching to "Host Only" networking before changing locations, and Parallels still hangs.
So, it hangs with both "Host Only" and "Shared" networking when changing location.
EDIT: This problem is reproducible every single time for me, so if there's anything else I can do to help track down the cause, then I'd be glad to help.
