Not sure if proxy support is working, at least here at work it is not, and I still get the same errors (because of it I suppose), although they renamed are no longer designated as "unhandled".
Post a screen shot :P
You liked those, didn't you?
I am guessing you set the proxy param in setting also? I don't have a proxy so I can not test it really. Never used one either so not sure how they work. I just let the user set the param and pass the param on to the HTTP client.
