I was so excited to find the exact answer to my little difficulty with the missing Advanced Tab! So I changed the AdvancedTab value at HKCU\Software\Policies\Microsoft\Internet Explorer\Control Panel.

But nothing changed. Now what?

I used Spyware Nuker to clean up a few cookie and register probs but
have no idea what to look for next.

I'm running NT4 SP 6 and IE 6 (Upgraded from IE 5 to try to fix this.)

If you can help me I can return the favor if you ever need help with
the drum card on an IBM keypunch.
