Unable to connect with Oracle DB due to Pop Up blocker

Hi,

I am not able to connect with Oracle ISIS Db due to some pop up blocker turned on. Although in the internet explorer my pop up blocker is turned off but still getting the issue while replaying the script in Vugen 12.53. I m getting error message like  - 

function handleError(message, URL, lineNumber )
{
<!-- window.alert ('Error ' + message + '\n' + ' at line ' + lineNumber + '.\n'); -->
document.write('<h2>The ISIS session you requested could not be launched because ');
document.write('you have a popup blocker turned on.<br>&nbsp;<br>');
document.write('Click <A href="how_to_disable_common_pop_up_blockers.htm">here</A> for Pop-up Blocker Help</h2>');
return true
}
window.onerror = handleError

Does it has something to do with Firewall issue??Plz help!!!

Thanks in advance.
