Everything is fine in design mode but once I hit preview or publish, only half of my menu is clickable.
Could you post the URL for your site, along with an explanation of what you're expecting to be clickable that isn't?
I am having the same problem. Two of my menu bar options (made from the widget) do not work in preview. They are all top level page buttons.
When i click Publish/Manage a validation code comes up for my adobe id (AUTH_UNKNOWN_ERROR)
Please see the following topic for the solution to the problem you're having: http://forums.adobe.com/message/4318719
Thank you that sorted the problem.
