[Plugin: bbPress] Forum Cut Off

I’m having the same issue when viewing my forum on a mobile device (seems to work fine otherwise). Using WP 3.5 with Twenty Twelve theme and bbpress 2.2.3. I can’t offer a link to the site because it’s only open to members, but if you visit jrold76’s site, you’ll see the problem. The text entry box to create a new topic or post a reply gets cut-off on the right side and there is no way to scroll over. In my case, it’s not possible to access the submit button because it also gets cut off.

Any suggestions or help would be much appreciated.
