lol..I have experience similar symptoms not exactly the policy page although I remember I got the web policy page while back once, but when posting the actual post goes no where, because of this I have developed a simple technique to save the text I have typed in case it is lost but happens occationaly not all the time.
Thanks for all the reply. This is the first time it happens to me. Regarding the session timeout, it never happens to me. I can switch to VPN (with no split tunneling) and back and the session continues.
Yes, from now on, I will copy and paste my reponse to NOTEPAD before hitting "Post" :)
