Hi Rob,
To replace the Text Area with MSIE HTML edit control is possible and is proven, but like what I have stated "caution must be taken" for CMS application. MSIE HTML edit even makes ETP/modETP less CMS capable. Style and layout are placed in the content, plus images are linked via absolute URLs. I have put up the above post since I have experienced this problems first hand. Its my unbiased opinion to people who want to implement a real CMS solution with a WYSIWYG and not to use the MSIE HTML edit route. The use of MSIE HTML edit control on modETP suits our needs and situation, which is ok by me.
Although I would discourage others from using it, especially in the context of CMS. Hopefully other people (not just Guan) maybe in a situation wherein they can build a WYSIWYG editor that is ok on general use and CMS use. Thanks for understanding.
