Kurt,

Very Cool!  I wasn't familiar with the showDocument method.  Quick question:

I'm not currently using an http server ... just "file://" URLs for a demo on a
laptop.  When I use a "file://SomeOtherAppletPage.html" as the URL, I get a
Netscape "Access Denied" error.  The SomeOtherAppletPage.html page and its
applet are browsable and operate just fine when I launch Netscape directly to
it.  I've tried "_top" and "_self" as parameters to showDocument with the same
effect.

Am I missing something security-wise?  (I've allready run the "Preferences
Wrangler" against my Netscape v4.03, JDK 1.1 upgrade).

Once again, thanks for the valueable pointers.  :-)
