Perhaps try Netscape if you are using IE, or IE if you are using 
netscape or upgrade your browser.  The submit/upload function uses 
some technology that is fairly "new" to old browser technology but 
was introduced a pretty long time ago, it should work pretty well on 
an up to date browser.

It is also possible that you've run into a posting problem, were no 
sites will post any html form.  I've run into this problem sometimes 
using a cable router/modem.  I can browse and click links just fine 
but when i click submit buttons I get DNS errors.
<p>
what is the error that you get when this happens?
