The only other simple explanation I can think of is that Opera is not parsing the POST back to the server properly. It may occasionally get confused by the mark-up tags that TBN uses or some unusual combination of punctuation.
Next time it happens take a look and see if you were using any particular elements of the TBN mark-up tags OR punctuation that could have been badly handled by Opera.
Barring that, I would recommend that you do a 'View Source' on one of these reply forms and post the HTML on the Opera web-site for them to chew on. Must be some specific combination of issues.
Good luck with it!
