I am the author of a CiviCRM extension that needs to disable, depending on configuration, the URL tracking and open tracking checkboxes of the mailing form. In version 4.4 this was accomplished using hook_civicrm_buildForm (CRM_Mailing_Form_Settings) and calling the freeze method on those elements.
This form hook is not getting called in version 4.6, so how would I go about doing this now?
Thanks for looking.
