Easy enough. Give your pop up links a name variable:
Code:
window.open('mywin.htm','name','height=255,width=250, toolbar=no,directories=no,status=no,menubar=no, scrollbars=no,resizable=no');
When you make the links... just make sure NAME is the same. That's it.
Or if you are using JS to make the pop up:
Code:
TheNewWin = window.open('','name','height=255,width=250, line toolbar=no,directories=no,status=no,menubar=no, scrollbars=no,resizable=no');
Same thing there though, just different pop up controls
