problem with Internet Explorer

I have a frames problem with internet explorer,

when I use this java code in a frames page:

URL newLocation = new URL (WiskhintLibrary.servletURL +"/"+ sessie +"/Hoofdscherm.html");

this.getAppletContext().showDocument(newLocation);

The program should now go back to a no frames page

but explorer doesn't kill the frames, and netscape does.

can anyone help me with this problem?
