I use proxies quite a lot and needed to have the proxy change function change all the proxy settings. so I have modified the proxy.kmm to show and ask for all the settings.
I am quite new to the macro language so I may have made some mistakes (or quite alot) could you all have a look and let me know if anything needs any changes. I currently works quite well on my 1.1.2 version
Cheers Rochey
PS. The faces are ": s" without the space, I can't seem to get the txt to show properly.
