Sweet!

 

In addition to that, this is what I had to do...

 

On client init, 

 

//Allows for the ATOMICSELECTION Attribute to be used, which selects the element as a single unit

//http://msdn.microsoft.com/en-us/library/ms537835(VS.85).aspx

document.IDM_ATOMICSELECTION = true;

 

 

When the user wants to add a field,

 

 html = "<div ATOMICSELECTION='true' UNSELECTABLE='OFF' contenteditable='false'>" + field+ "</div>";
this.CE_EmailBody.PasteHTML(html);     

 

Using the  IDM_ATOMICSELECTION property only works in IE unfortunately...

 

Thanks for your help!
