Thanks, Adam.
Also note that I discovered if I do this (IE ONLY):
editor.EditorWysiwygModeCss = "_account/ui/samplesite.com.css"
Then this style sheet is applied:
This is great!
In this case, the one exception I have found is that the body font size CSS attribute is not applied.
Thank you for investigating this issue. It is a major one for us.
