Pownce on the Wii

I tried to use Pownce on my Wii and it does not work. I realize this is probably pretty far down the list of 'to do' but i thought I would report it anyway.

the site comes up just fine, and i could log in. When I went to send a message, the form works, both text and drop down list. however when i hit submit, the block that the message form lives in reduces to a few pixels high. no message is posted. the page can be reloaded and it will return to how it looks.

the wii uses an opera based browser.
