Trying the same thing in FF now: Okay ... that's really retarded, and really an improper way to use punctuation. I put two spaces using the other browsers and it's fine. It's still a FF thing, I think. Although I do notice that Safari only puts one space in anyway, even if I type two. edit: well, mystery solved, except that is going to be really annoying for me to not put two spaces after periods, question marks and exclamation marks.
