Cannot Save Writer Page in Zoho Notebook

Cannot Save Writer Page in Zoho Notebook

I cannot save the contents of a writer page in my notebook.  The save button do not appear to be active.  I have tried using ctrl-s, but that does not save the document either.  I have tried on both IE6 and IE8.  (In IE6, the writer page does not appear to load properly).  Any assistance would be greatly appreciated.
