When I open the document editor all I see is HTML code?

The document editor is currently compatible with the Firefox (version 2 upwards) and Internet Explorer (version 7 upwards) browsers. if upon opening the document editor you see HTML code rather than the WSIWYG editor then it's because you're using an unsupported browser.

In the future we'll make the editor work across more browsers but for now you'll need to use Internet Explorer or Firefox.
