Only over the last few days (i.e. not before) I have discovered that the LAN Settings box for "Use a Proxy Server" keeps being automatically set which I do not want as this prevents access via Citrix. When I unset this box Citirx works fine until the next time that Windows 8 is loaded.
The machine is an ASUS Vivotab PC.
Some ideas how to get this setting to be permanent?
