@spidergal,
Now, wait a minute. There are two things you might mean by 'quote function'. If you use the quote button instead of reply, the whole post goes into a quote box with attribution. If you copy stuff, highlight it and hit the quote button above the reply box, the stuff goes into a quote box, but without attribution - unless you mean the post reference. That is, you get the same post reference that you always get when using the reply button. I bet you used one or the other. If not, it still happens that using preview can produce a box around everything, but I'm not sure it does it in every case.
I'm not sure that is clear to anyone but myself.
