In IE the link opens in a new window but it;s redirected to my home page.
It happens only from the search results page.
More than this the hits out counter is not working anymore

If you open my popular, new , cool pages with IE an error icon appears in the browser bottom corner ( http://www.cumpotsa.ro/directory/new.html )

As suggested I made this change in the script:

Near line 1249, locate
Code:
$htmlsrc .= "<a class=\"siteName\" href=\"" . $sites_array['site_url'] . "\" onclick=\"location.href='./out.php?ID=" . $sites_array[site_id] ."';return false;\">";
Change to
Code:
$htmlsrc .= "<a target=\"blank\" class=\"siteName\" href=\"" . $sites_array['site_url'] . "\" onClick=\"javascript:window.open(\'out.php?ID=" .$sites_array['site_id'] ."\';return false;\">";

Didn't change the first one because it results in an error...and I have no idea how to debug it.

Strange thing is that if I change above code to the original it will work fine in counting the HitsOut in firefox but it will just redirect to main page in IE (including from Popular , New etc.)

Later edit : In Firefox the generated link to the site is : http://www.cumpotsa.ro/out.php?ID=xx
In IE it is : http://www.cumpotsa.ro/directory/out.php?ID=xx
