Problem z framom

Imam problem s framom.
Moti me to da je ob strani v sivem odtenku vidti tisko, ki je za pomoč pri pomikanju na strani navzdol.
Koda tistega dela strani:

<table width="95%" cellspacing="0" cellpadding="5" border="1" bordercolor="#FFFFFF" height="943">
<tr>
<td bgcolor="000000"><blockquote>
<table>
<tr><td><a href="banners.htm"><img border="0" src="images/banner_150x40.JPG" width="150" height="40"></a></td></tr>
</table>
<strong><td width="100%" height="941">
<iFrame src="http://localhost/phpbb3/index.php" width="100%" height="100%"></iFrame>
</td></strong>
<td bgcolor="000000">
<table>
</center>
<tr><td><a href="banners.htm"><img border="0" src="images/banner_150x40.JPG" width="150" height="40"></a></td></tr>
</table>
</tr>
</table>

Zanima me tudi, kako bi nastavil da je višina frama enaka višini strani, ki jo dodajam(100%).

Ifrejmu nastavi style ali id in nato preko css nastavi:

overflow:hidden;
