Just had a strange experience with Opera 6.04 in replying to a post.
When I returned to the lounge my post was headed with the original post name (preceded by re and followed by -MULTI- and the post name again. When I tried to edit the post in Opera, it just added more MULTI bits.. finally reverted to IE to fix the haeding.

Incidentally, using Opera, unread posts appear red, whereas using IE 5.0 they appear yellow. Strange. eh?
