Problem facing while Login....

Do you use the back key or back button often? I think the problem is related to use of that; I assume you understand what I mean by back key or back button. I use them a lot and a couple of days ago I was logged in and then I went back to a previous page and then I was not logged in. I will try to remember the details the next time that happens to me.

In the past month I have had to log in at least once a day for most days. It seems to have begun happening when I was made an editor for this site but maybe that is just a coincidence. If we continue to have the problem then it is probably worth reporting again in the future.

nope that didnt worked.. now its working fine...
