There is no problem for PasteHTML('This is a test!')"
But if the content of pastehtml is as following:
<a href='http://localhost/d.aspx' target='_blank'>http://www.google.com</a>
after PasteHTML, it was changed to following automatically by the cuteeditor behind the scene<a href='http://localhost/d.aspx' target='_blank'>http://localhost/d.aspx</a>";
works in firefox, but not in IE
