When working on a document in Zoho projects I use Headings (1,2,3, etc), when I save, close and re-open the document the Headings are still set as I originally chose but visually they are all mixed up.  So for example "Heading 1", the largest, will appear so small I can't read it.  I will have to reslect Headings to return them to original look.  Using IE 8.
