It's jumping vertically.

I'll try fiddling with it tonight.   Is this a common problem with IIgs
monitors?  Would the vertical sweep generator going bad explain the
headaches?  It's not just a slight jump in the image now and then
(although that does happen), I swear it also starts to get hard on the
eyes as well.
