That does not happen to me with Merovingian dot club unless I open in a new window or open in a new tab or hit the back button

If I am logged in and just hit reply to a comment it works normally

And by back button I do not mean the one provided be merovingian dot club but the back button provided by the browser

As long as I do not open a new window or hit the back button and I am already logged in I do not have to authenticate again
