windows 7 32 bit fully up to date. profile from 02/04/2012, probably v10.0. this used to be a simple task when you changed hadrdrives. not anymore with your daily changes. what happened to the instruction i got from your site on 2/24 that says "simply copy and paste profiles folder over the new one" Netscaper since 1994.
