refreshing opener page won't work.

[lovekang]

I have opener page which shows data from database.
the popup page updates the data.

the opener page is just blinking.

of course in the popup page I tried to refresh the opener by
window.opener.location.reload();

and I've tried the below in the opener page.
<%
response.setHeader("Cache-Control","no-store");
response.setHeader("Pragma","no-cache");
response.setDateHeader ("Expires", 0);
%>

only when I right click and select "refresh" , the page is refreshed.

what's the problem?
