You can try this code and modify to your link and size:

<a href="http://www.some_link.com/" onclick="window.open (this.href, 'child',
'height=400,width=300,scrollbars'); return false">some 
designation</a>

use or not use the scrollbars entry.

Thanks Kobra
Will try this and post again later
All the best

Thanks Kobra but I'm still having probs......
Zen 1.2.7
functions/banners.php
Line 154....This is what needs to be altered, but your suggestion doesnt seem to work....errors
{
if ($banner->fields['banners_open_new_windows'] == '1') {
$banner_string = '<a href="' . zen_href_link(FILENAME_REDIRECT, 'action=banner&goto=' . $banner->fields['banners_id']) . '" target="_blank">' . zen_image(DIR_WS_IMAGES . $banner->fields['banners_image'], $banner->fields['banners_title']) . '</a>';
}

What you have posted is php code and what I provided is html code.

I really am terrible at code, especially php.

The code posted is some of that that builds the page dynamically from parts of other files. Some where in these calls there exists some definition of the window size/control.

By my posting back this will bring this back to the top and hope that another with more php expertise can assist.

Bump :)
I am wondering how to do this also.
