[support] logging using lynx browser

I am trying to log in my site using lynx text-based browser in some occasion. But it seems like not working for me. It stays at login page even my credentials are correct. I tried logging to drupal.org, it is working fine. I am wondering if there are any settings I need to configure. Because it is working fine on Drupal 5 based websites. I am currently on Drupal 6.6. Thanks.
