Well on that page the problem is different.

When I paste

<script language="JavaScript">
<!-- Begin
document.write('<a href=\"mailto:contact'+ '@' + info.com\">');
document.write('contact'+ '@' +'info.com</a>');
// End -->
</script>

 

in the HTML view then I switch to WYSIWYG view and then to HTML view again my javascript code has gone and is replaced by a simple <a [email protected]">[email protected]>[email protected]</a>

 

Any idea ?
