You were correct pevergem. I knew I wasn't losing my mind when I discussed this in the RotS thread. Apparently I have a newer version of Firefox at home.
I upgraded this browser from 3.5.9 to 3.6.3 and the multi-quote checks were unchecked upon posting a multi-quote post.

Solution lies in upgrading your browser. It is not a faulty board.

Thx pever.
