Cheers for that Ian,
I had found that, and also discovered that if you add the styles during the run time of the HTMLEditor3 configuration GUI under the styles tab (you can add individual styles here - but again, one by one - one property at a time) - that the javascript file is replaced with the styles that you enter at that stage.
None of which helps with just loading the styles from the stylesheet. I know that the HTMLEditor has referenced my site stylesheet, because it has adopted the 'body' tag which is defined in that stylesheet.
Mind is too frazzled to think.
Thanks,
