Is anyone else experiencing this problem?
Also, do a clean up of your PC. I was having similar problems with gallery login/ where it would log me out once I come back to the forum page. I tried it from my Laptop and problem disappeared. So, only difference was that my desktop had some spyware/junk software installed which was troubling the IE and hijacking the browser. Laptop does not have any such issues. When I ran spyware cleaners like spybot, ad-aware, hijackthis and then problem went away.
On the other hand, if everyone sincerely RESPECTS other people and their opinion, we would not have such issues. People have this problem of denouncing something which they don't agree with and calling it the end of the story. They don't want to discuss the topic on its merit or for the sake of discussion. I will let GF answer your reply.
