Just curious - would your IP changing or consistently logging in/out with different IP addresses be a cause for concern to TNT, if you weren't doing anything suspicious otherwise? So far every proxy I try begins to act up after a few minutes so I wanted to know.

Also, if anyone does know of some free proxies that don't stop working (refuse to accept connections, according to my browser) after a while, please let me know! Hidemyass has been really helpful in terms of proxies that actually load webpages but after a bit they go the same way as the other proxies I've used.
