Header footer toolbar missing

Apologies if you have already read this, as I posted as a reply to a thread which is why I think I have not yet received an answer, so posting it again.

I have lost my header/footer toolbar. It does not automatically appear when I am in a header or footer, it is most frustrating.

Whilst in the header/footer pane I can go into View/ Toolbars/ Customize toolbars and see the header/footer listed but I cannot select the check box to make it display. Have also tried to re-set the toolbars.

The only way I can get any thing like automatic page numbers, fields etc into a header or footer is to use Insert Field or Insert Autotext, it is most frustrating not having the header/footer toolbar.

Any ideas?
