When I connect to my workplace LAN I have to use a company proxy. This proxy is set as usual in IE's LAN settings.
The picture below (taken from Google Images as my Windows is not English-localized) shows the typical configuration
The problem is that when I check the "Use a proxy server..." checkbox and hit OK (my configuration only differs from the screenshot's by proxy's hostname) the settings are not applied.
It means that if I re-enter the LAN settings I see again the checkbox unchecked and the
Address field greyed. No matter how many times I re-enable it, or close (with OK)
Internet Settings window, I still can't enable proxy.
Fortunately Firefox has its own independent proxy setting window, but I don't like this behaviour in Windows.
I'm unsure whether this is related or not with recent IE update to version 10.
The question is obvious: how can I fix that?
