Hi, Are you not using the "Name" attribute of the window.open method? e.g. var wnd = window.open("http://www.google.com.au", "MYWINDOW", ... ); Even with a page refresh, when you perform this, IE will look for a window with the specified name and return the reference back to you. Of course, this means that you need to perform a navigate to do this, but it depends what you are displaying in your child window? Hope this helps, Andy
