this is a bit of a weird problem, but entirely repeatable (for me at least).
1) subscribe to a thread
2) when it receives a response open it (anchored at the new post) via the email link
3) try to quote that message
invariably i get a blank reply box rather than the quote i expected. clicking on the link above the reply box (for example My Thread in "Downhill | My Thread") then quoting the message again produces the expected behavior.
this blank quoting behavior may happen at other times too, but for now i just know that i've seen it several times by the above method.
