How to capture an click event from window.open

Hi,

Just wondering how I can verify a user has clicked a link withing a window.open link.

w = window.open( url ,"TableLookup" , "height=340,width=500,scrollbars=yes,resizable=yes,menubar=no,toolbar=no,status=yes" );

so w is my window.open...

I want to verify the user has click something in the new pop-up window...
is there a way of finding this out?

Thanks in advance

 

no, not if the window that has been open is displaying a page on a remote server.
