I wasn't sure whether to post this issue for UC Ticket or Captcha...

When the UC TIcket module is enabled, the captcha appears at the top of the contact form. When the module is disabled, the captcha appears correctly just above the submit button. Using the captcha "flush the captcha placement cache" has no effect.

Using latest 6x versions of all modules: Drupal 6.20, UC Ticket 6.x-1.0-beta6, Captcha 6.x-2.4
