Hi Guys,
I am really late to the v8 beta having just come in on 7.892 but liking it alot.
This isn't a critical issue and seems similar to some closed threads regarding problems with Safari in earlier versions but...
1. Ran the installation wizard using IE8 on Windows 7 x64 during which I changed the LAN IP. After clicking Finish went to reconnect on new LAN IP
2. After logging in I was presented with the Installation Wizard again. Clicking cancel resulted in the Web Admin console showing up with all the settings I had entered during the first run through.
