I m having a hard time figuring out how to do something in IE that is 
fairly easy to do in NN/Moz.

What I want to do is have some Javascript code in one window open up a new 
window, and then be able to rgularly interrogate the url currently being 
displayed by that second window.  In particular, if a var named
	SHARED_WINDOW
holds a reference to that second created window, then I want to look at 
the value of
	SHARED_WINDOW.location.toString();

In NN/Moz, all you have to do to is put in the request
	netscape.security.PrivilegeManager.enablePrivilege
("UniversalBrowserRead");
in the same function as the first line above, and if your script is signed 
(or if you have enabled codebase principals), then the user will be 
prompted to grant permission.  I have tried this, it works great.

But how do I get this to work in IE???

I have tried this in IE, and I always get security errors when I try to 
interrogate the second page as soon as it is anything other than 
about:blank.  The security setting in IE (e.g. low, medium, etc) has no 
effect on this.  Indeed, the following URL seems to indicate that this is 
fundamentally impossible in IE:
	http://msdn.microsoft.com/library/default.asp?
url=/workshop/author/dhtml/reference/methods/open_0.asp

Please tell me that this is not true, that there actually is a way to do 
it!!!

I cannot believe that IE does not provide something equivalent to NN/Moz 
for greater priveleges...
