In drupal 6.15, when creating an event using event module (6.x-2.x-dev) and with WYSIWYG module (6.x-2.x-dev), the first time the 'create event' screen is rendered, there is no WYSIWYG editor shown. It is not until after the user hits 'preview' that the WYSIWYG editor gets rendered
WYSIWYG editor is rendered properly when creating all other types of nodes (story, page, etc)
