TINY MCE HTML EDITOR is adding random code to my code!? - Joomla! Forum - community, help and support

hello everyone,

tinymce editor html editor adding tag , erasing closing tag on last list item!!..

<code>
<ul id="acdn">
<li> <a> <img src="templates/sd/images/integrate.jpg" border="0" />
<p><strong>a</strong><br /> blah</p>
</a> </li>

<li> <a> <img src="templates/sd/images/integrate.jpg" border="0" />
<p><strong>b</strong><br /> bleh</p>
</a> </li>

<li> <a> <img src="templates/sd/images/integrate.jpg" border="0" />
<p><strong>c</strong><br /> blih</p>
</a> </li>

<li> <a> <img src="templates/sd/images/integrate.jpg" border="0" />
<p><strong>d</strong><br /> bloh</p>
</a> </li>

<li> <a> <img src="templates/sd/images/integrate.jpg" border="0" />
<p><strong>e</strong><br /> bluh</p>
</a> </li>

<li> <a> <img src="templates/sd/images/integrate.jpg" border="0" /> </a>
<p><a><strong>f</strong><br /> blueh.</a></p>
</li>
</ul></code>


the last chunk contains tag f , word blueh should
<code><li> <a> <img src="templates/sd/images/integrate.jpg" border="0" />
<p><strong>f</strong><br /> blueh</p>
</a> </li></code>

why changing code? have tried toggling editor, making changes , applying them, reverts incorrect code...

there can remedy this?

install jce , abandon tiny. jce lot better , won't mess code.
