Adam,
It seems to be happening within the <head> tag. The editor at your link doesn't seem to show the <head> tag in the HTML view.
All I did was load the content in the editor, clicked on the HTML view and I see this style sheet being inserted with the <head> tag.
<link href="http://cutesoft.net/CuteEditor_Files/Style/SyntaxHighlighter.css" type="text/css"
rel="stylesheet" isprelink="true" />
On saving the content, the stylesheet remains in the HTML.
What is this stylesheet for?
Thanks,
