insert table doesn't work. Anyone else?

So I have three centered paragraphs in my edit window:

<p align="center"><strong>WYSIWYG</strong></p>
<p align="center">in </p>
<p align="center"><u><em><strong>FireFox</strong></em></u><br /></p>

I position my cursor in the first character position and click the 'insert table' toolbar item. I just click enter to select the 3x2 default.
Instead of a singe 3x2 table I get TWO 3x2 tables. Further, my first line has been duplicated. Sort of. The cloned 'WYSIWYG line is not bold.

If I try and insert a table with the cursor positioned anywhere BUT any cursor position on the first line it works. If I switch to IE it produces the identical error.

The html looks like what you see below.

<p align="center"><strong>
<table cellspacing="1" cellpadding="1" width="200" border="1">
<tbody>
<tr>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>
<tr>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>
<tr>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>
</tbody>
</table>
WYSIWYG</strong></p>
<table cellspacing="1" cellpadding="1" width="200" border="1">
<tbody>
<tr>
<td>&nbsp;</td>

<tr>

</tbody>
</table>
<p align="center">WYSIWYG</p>
