Clownfish - tried what you said, and deleted a few entries from the registry but IE5 still remembers ALL the auto-complete. (when I went back in the registry again although I had only deleted a few values all of them had gone). It would be handy just to delete a few (the dirty ones!) rather than clearing the whole history (which does work). Must be stored somewhere in IE5, not the registry as I have searched the registry for some of my entries and it does not find them!
