Did a little experiementing tonight. When I turn off Java scripting the keyboard pops up just find and I can type in the reply box BUT when I SUBMIT nothing happens or I get an error message "We're sorry, but there's been an error in our system, and we can't complete your request. Please report this error to us, using our feed back system. Thanks!" "Message: Page not found:Argument 'id' was not passed to the query string."
Hope this helps the administrators narrow things down. The Kindle Fire runs an Amazon browser version 1.1.0-84. Thanks.
SAME problem HERE!

I really hope they try to fix it for us...
