Very Sorry, was just letting you know I have done the same.
I have look at yours and It's great.
Ours serves a more specific purpose. We have two Proxies one filtered, one unfiltered.
Our students found out the UnFiltered Proxy and was using it for all sorts.
So I HARDCODED the proxy in, which is SPECIFIC to our school.
Yours, and this is ment with no disrespect could still be altered by clever students to use whatever proxy they could find.
It's still a great piece of coding very nice and easy sat the the system tray, you have to physically run mine.
Sorry for intruding on your thread.
