I just moved into a new house, and now my screen has the bouncies too.
But, it seems to only be happening in the afternoon - I put a voltmeter
on the AC, and it seems low - i caught it down around 103 at the lowest,
with moderate screen bouncing. I imagine the voltage is jumping up and
down around there, with all the air conditioners running this time of year.

The best cure for this would be a UPS, but as I can't really afford one
right now, so i'm looking out for a good deal on a constant voltage 
transformer.  Mind you, a surge protector won't help as this is the
opposite problem - drops in voltage rather than rises. Something else to
watch for, anyway.
