I am looking as I type, and you are absolutely correct.  Now nuked.

I think it does, at one point it reported an identity error.

Not impossible, but not very likely either.  I have been known to extract 
that keytop as it is such a pain in the ass.

it says error 1 in the popup.

From the crash file before I nuked it:
SourcePackage: ntp
ErrorMessage:
 subprocess installed post-installation script returned error exit status 1

No argument there, but if tripped at high speed, then all axis's will need 
rehomed, destroying the present calibration.  The button on the screen, or 
the esc key, does a graceful stop using the programed accel/decel rates so 
it doesn't lose position.

Sometimes I wonder, emc needs more math than I ever got in my 8 years in 
school back in the '40's.  OTOH, as a retired broadcast engineer and a 
C.E.T., I have done fairly well.

Not automatic, just the advisory that its needed, a different problem, but 
I may have it go ahead and do it in the background while I am doing other 
work on the emc screen.  A relatively safe operation until the last couple 
or 3 months.  Now, with 4x as much memory in that box, it may not happen 
again.

Thank you very much Nils, I expect this has solved my problem.  And I 
learned something at the same time, so a tip of my University of Hard 
Knocks baseball cap is sent in your direction.  ;-)
