You got me thinking about the DOC types so I did some poking around and found an entry in the FCKconfig.js file where the DOC type can be specified:
I changed the FCKConfig.DocType = '' setting to:FCKConfig.DocType = 'http://www.w3.org/TR/xhtml1/DTD/xht...tional.dtd">' ;Once I added the DOC type settings here, the the font sizes show the same in the fckeditor window as they do once previewed and saved! Finally. I have been messing with this for days.Thanks again for your help in pointing me in the right direction. This is a great site you have here with a ton of great info!
