I updated to ZASS 8.02 today and what a pig and I'm a fairly experienced user. I had problems with IE7, sites wouldn't connect among other issues. I had problems with e-mail. I had slow system response.
In the end I had to uninstall it and reinstall the older version. It still needs a lot of work before I'll try this again. I am using Windows Vista Home Premium.
