Parse errors

If there is a parsing error:
open a browser,
delete cookies,
log-in to mail.yahoo.com,
if there is an invite to download yahoo tool bar or something else, deal with it somehow (I clicked "no thanks, go to my mailbox").

Yahta 4

New version is done. Before using it login to Yahoo and switch the interface to the new one with AJAX.

New version coming...

There is a major change at Yahoo's site. Old parser doesn't work anymore. I'm working on the new Yahta.
