Occasional problems posting or replying to threads in IE9

[aucrawford]

When using IE9, sometimes when you go to reply to a thread or post a new thread the user will be unable to post. The user will instead see an error messages stating that a minimum of 10 characters must be entered. Even when turning minimum characters to 1, this error still happens. Also I have noticed that the cancel button will be hidden on the page before trying to post, and it doesn't seem to be hitting the ajax.php file.

This does not happen consistently, sometimes if you refresh the page it will go away.
