OH GOD MY EYES ARGH

Dear administrators of this fine board,
when I look at sjis, all characters are in bold,
which makes the art look horrible.
However, when I'm in full-thread-view,
things look as they should.
Why is this? I have the Mona font installed
and I'm using Firefox.
Please fix it if you can.
Sincerely,

    Anonymous-san

Doesn't the P in MS PGothic stand for "Proportional"? And if so, wouldn't plain MS Gothic which is monospace be a better choice for an "SJIS ART" font?
