Actually, I haven't changed the CSS at all from the very beginning, so it's not like it just got "infected".
Oh, wait... that's not true. I wonder if this is a result of putting the CSS in a separate file. See, Wade, I told you so. :-)
I'll change that back; it's probably the root cause.
Various types of UI are on the TODO list. I dont' particularly care for CSS either.
What browser are you using? I shouldn't think that CSS would affect the wider/narrower functionality. That disturbs me.
