Ed:

Did a bit of scanning on Google about "ctrl-alt-bksp" but can't honestly 
say that I got much out of it since it was wrapped under threads 
involving more serious failure issues. Let me give this a try the next 
time I sit down with the Linux box as, though I agree that a "better 
solution" is in order, I will quite happy for the near-term to just have 
a way to kick the puppy into being correct.

Many thanks for the suggestion,
Paul
