Vista/IE7 further showDocument focus issue with named targeted windows

Essentially the fix for 6946479 will not work properly for Vista/IE7 specifically. It checks to see if we're on a Vista+ version of windows. If so, UAC limits us to certain options. We can't get a list of IE windows and cycle through it for example. The solution was to set focus on the applets parent browser window before we call navigate. This works in most cases. However, for some reason, with IE7 it only works the first time we call navigate on a named targeted window. (when we open it initially that is) Any subsequent call to navigate will not cause the named targeted window to gain focus. This means we're left with the applet parent window on top of the focus stack.

We are Applications technology Integration team and we are a bridge between EBS and underlying technologies. The EBS code is generally very complex and we remove those complexity and provide a simple testcase to technology owners (in ur case JDK) which can be run standalone outside of EBS. This helps in reducing turnaround time for technology fixes.
I confirm that the standalone testcase provided reflects the exact problem faced in EBS. Please provide a fix for the standalone testcase already provided.
