Francis,

Are you using a 1950 color monitor?  The problem you describe sounds like
the one I've been experiencing (and been trying to solve) for several months
now.

George,

I give, what's the problem?  I've been in contact with Commodore Customer
Satisfaction and _they_ don't know what it is.  They say they are not even
aware that such a problem exists.  They even shipped me an advance replacement
unit 'cuz my dealer can't help me, and it has the same problem.  I've now
been through no less than four (4) 1950's and they all suffer the vertical
jitter problem.

I've found, at any rate, that it's highly sensitive to temperature.  Cool the
room down, cool the monitor down with a fan on top of it, heat the unit up
a bit by blocking off part of the top vents, and viola' - the problem goes
away (or, at least, the symptoms subside).

BTW: So far I've found Commodore to be one of the most responsive
manufacturers I've ever encountered.  Now, if they can only get me a less
nervous 1950 :-)
