Resizing of the TextArea on border or scrollbar

Hi,

I have created a html page from Java and I have added a .js file which
can resize a TextArea inside the html on mousedown event.

<script src="C:\temp\resize.js"> </script>
<table> <tr><td onmousedown="javascript:resize('trinput',event)">
<TEXTAREA NAME="input" id="trinput" COLS=40 ROWS=60>
my textarea here
</TEXTAREA>
</td>
</tr>
</table>

But now when I click on amny of the area of tes TextArea the textarea
starts resizing.

Can I do something like only when the mouse is down over the borders
of the <td> or scrollbars of the textareas only then resize script
should get called ?

Please help !

Cheers
Nick
