May I also ask anchor question?
I tried it on the pages with links you asked and it produces the same wrong result.
Insert text shown bellow in HTML mode, Click Normal and HTML back - text will be converted to not well-formed html.
The reason is the custom attribute "xpath"! Without it - everything looks OK
<a href="#" xpath="." onclick="return false"><img src="image/AddButton_Up.gif" border="0"/>Add Task</a>
