Thanks, but...
Thanks dfobert,
I'm going to have to file this somewhere in case it happens again.
I managed to get out of it by restoring my virtual machine file from my Time Machine backup. Had to go back a few months. Fortunately, even though the information on it is critical, it only changes in spurts, and I've yet to find that I've lost anything valuable.
If it happens again, I'm going to try your suggestion to see if it gets me out the jam.
Thanks,
