Clear buttons do not work

Dear folks,

as I told you several month ago, your "Clear the textarea"  and "Clear 
the URI" buttons at http://www.w3.org/RDF/Validator/ are broken.
Unfortunately nothing has changed since my report nor did I receive any 
reply.

I would be very pleased and thankful if you could fix this problem in 
the near future.

Best regards

Frank

Hello,

I noticed that the "Clear the textarea" and "Clear the URI" button at
http://www.w3.org/RDF/Validator/
do not work for me.
The other buttons work though.
I am using Mozilla Firefox 1.5.0.7 from a Scientific Linux distribution.

Best regards
