Zoho Writer exports .docx, Word 2007 only saves as 97-2003, loses bullets!

So, I import a small .docx file and Z Writer displays it perfectly. It includes two bulleted items. I save it as .docx. When I export it as .docx, the download dialog box only offers to save it as 97-2003 format or "all files". Neither one preserves the bullets. Any idea why (Win XP Pro, Office 2007, all patches) this happens and why Word 2007 is not offered?
