I have a simple page with HTML text and a one section at the top for the header. All looks OK in the GUI, but when I preview the page in a browser (F-fox) the text is broken into two columns.

To be able to help you, I need a DEMO project (.wbs file) so I can see all your settings.

I do not need the complete project because that will only take more time to figure out what you have done.
Basically, I just need a small project with one page and object(s) that are relevant to your question.

For further details about how to share a project file, please see this FAQ:
