I installed NSW 2003 a few weeks ago after my Norton 2002 was up for renewal.
All seemed fine at first but after running for a couple of days my NTL internet dial up "user" window failed to start an internet connection because the usually pre-filled dial up window was blanked and greyed out.
I did a restore to before NSW 2003 was installed and when my internet applications were working fine. I could then access the internet again and my NTL dial up "user" window was once again pre-filled with my details and NTL's dial up number.
When I reinstalled NSW 2003 again later I had a reoccurance of this problem and have had to ininstall NSW 2003 again.
