I have a number of members using Opera (it's a Web browser)
With Sidebar on the left it causes everything to get centered on every other page that does not specifically have align="right
The fix is to remove the last align="center" in sidebar_leftopen.tmpl
##### In your /templates/default/sidebar_leftopen.tmpl CHANGE THIS
echo <<<UBBTPRINT
</td>
<td align="center" valign="top">
#### TO THIS
echo <<<UBBTPRINT
</td>
<td valign="top">
