It seems they all die pretty quickly, but the ones I mentioned weren't dead when I tried them.
Or if they were then Elite Proxy Switcher "lied" about them testing OK, because I tried them within minutes of loading and testing and deleting all the failures.
Proxy Switcher failed all but these two of the ones you posted in your previous message:
132.187.230.2:3127
218.249.83.87:8080
And whatismyipaddress.com saw straight through both of them.
I was looking forward to promoting this application to my newsletter subscribers, but it's beginning to look like I'm wasting my time, unless you have some concrete suggestion that will prove to me that Elite Proxy Switcher actually works.
