<< Did you ever realize that if you happen to push backspace while typing a message, that you can hit the "forward" button and it will take you right back to where you were, with the message still intact (I just tried it and it works for me with IE6/WinXP). >>
My post that complained about that said that it works fine with Anandtech (read my edit). However many other sites will give you this warning (or some similar warning):
<< Warning: Page has Expired The page you requested was created using information you submitted in a form. This page is no longer available. As a security precaution, Internet Explorer does not automatically resubmit your information for you. >>
Thus you lose your data.
