Problem, 1/21/2004

    4160 fans,
    We have a problem that is rendering the machine unusable. There is a 
large shift in the image when
you adjust the stigmator. This means someone had fooled with the 
adjustments, or the shields I put
on over Christmas are magnetized and have moved the beam away from the 
center of the column!
I'll figure this one out and let you know as soon as I know what's up.
    Until then, you may try using it, but I don't think you'll get far. 
If you had trouble with it recently
it's not you!
