karma,
I assume you're talking about the drop down "Address" bar in Internet Explorer?
Turning off "Autocomplete" should do it. In addition to the procedures you've already performed...Check these settings. While in IE, click on "Tools" in the upper left, choose "Internet Options", choose the "Content" tab, then select the "Autocomplete" button. UNCHECK the box next to "Web Addresses" and anything else you want. Click on "OK", Apply, OK, etc.
Hope this helps.

hello, i recently formatted my computer, and lost all of my browser settings. i reinstalled windows xp professional with the latest version of internet explorer (6 i believe). one of prior the settings was that my dropdown bar in IE would clear upon every restart. i already turned auto complete off, and set my history days to zero, but i know there was a setting where the dropdown bar would clear upon every reset, instead of me going through tools/internet options/ clear history. can anyone provide insight? thanks.
