I am having trouble getting this plugin to save. For some time, it would be stubborn and not save at all. It seems I have a 'better' solution: in rich-text-widget.js, I've replaced this line:
mode : "none",
with
mode : "specific_textareas",
It sort of works now. I click save once, and my visual editor turns to the HTML editor, and I click save again to actually save it. I would only like to click save once though and have it work. Any other ideas?
