Window.open is not working in IE8 fine in firefox

I having trouble getting pop-up window in IE. I have used following code. Its works fine in Firefox but not in IE6.

Code:

com.google.gwt.user.client.Window.open(url, "Admin ",
                                   "menubar=no," + 
                                   "location=false," + 
                                   "resizable=yes," + 
                                   "scrollbars=yes," + 
                                   "status=no," + 
                                   "dependent=开发者_开发百科true");;


Any Help greatly Appreciated 

It may be a little late, but IE (most versions) requires the second argument of window.open(URL, "window-name","") to have NO spaces, even though you put quotes around it:)

For example your code should change to "Admin_"
