Hi
I'm facing the some what similar issue with cute Editor and I'm able to reproduce the same on this URl
For me when I was toggling between normal mode and html mode it was copying the text from the <head> tag to <body> tag.
To reproduce this copy the below html in the html mode and switch between normal mode and html mode
<html>
<head>
This text gets placed in the body tag!!!
</head>
<body>
<br />
</body>
</html>
Any help?
Thanks
