Problem with closing a browser window

OK... something is a little odd there.  You're using an "&&" call between two find calls that will return an object and then you are using an "Exists" property off the object.  That just seems a little off to me.  Shouldn't you just have the first half of that and drop the "IE.Find" part? Otherwise, I'm not entirely sure what sort of object you're getting back as "&&" is a boolean operator.
