Options I would try:

(reasonable approach)I would fiddle with a stylesheet and
come up with your own stylesheet/css thing that worked
with your setup.

(shotgun to kill a bee approach)Buy a 20" widescreen LCD
from Dell when they are on special for ~400$ or less.
This could solve the problem you are having plus give
you a great screen. I would recommend other brands, but
there just hasn't been a better deal. If you have a
laptop, consider upgrading to a laptop with a screen
using 1680x1050 resolution or better.

Send screenshots or examples and that may inspire a whole
new set of replies.
