Hi Adam,

 

Sorry for the late response, was busy with 1001 other things ;)

 

Thanks to your sample i've tracked down the problem its seems our editor was enclosed by <div></div> elements in which

(as i just found out ;) an <iframe></iframe> element may not be nested, this caused the strange behaviour of the editor.

 

Again apologies for the late response and thanks for your excellent help!
