Any news?
Well we managed to change the default font and size (at least I hope so) to Arial - 10, but if I don't change the font and size manually the exported font (to rtf) and size are allways Times New Roman - 12. After changing manually the font is correct.
It may be because the html has no font tags unless you change the font, so when converting to rtf you just use your default font and size which is not the same as mine.
Should I change something else beside the css file in the EditorWysiwygModeCss property?
