Hi Simon ,
Thanks for your reply.
Here is what I am doing .
i) Call a window in a javascript of component A.
ii) in the window on click of a button I write the following code
window.opener.CallAlert();
where CallAlert is a javascript function of component A.
This all works fine  in a simple portal application
However , I have a strange problem , I have a DC , portal standalone module type. It has some four components , say a b c d
when I implement the same functionality in these componenets , on clicking the close button ,
I get the I.E browser promt .Stack overflow at line:0.
Its really strange for exactly teh same code is working fine , when i use a simple portal application
