I developed one application by using HTML,JAVASCRIPT & ASP. I used POPUP windows in my application. Its working fine for me in my system. But its not in our users machine. I checked the browser version. We both are using the same type like IE5.5 SP2. The problem is like this.<BR><BR>On popup window, upon submitting, the results should display on the main window. I used the following code for that in my popup program.<BR><BR>opener.location.href = "Main_Page.asp".<BR><BR>As I said, it working fine at my system. But for user, the search results are displayed on the same popup window instead of in the main window. what else I need to check. Thank you very much for your help. JY<BR>
