I probably added that so far back in the stone age that I have now 
forgotten it. Machine memory has been expanded with the machines over 
the last 18 years, and is at 8Gb, nominally 20x the 320 megs the 
original machine had in 1998.

I'll remove it and see how it runs tonight.  And advise.

Thank you Nathan.
